In do_bootm_states when doing BOOTM_STATE_LOADOS we use load_end
uninitialized and Coverity notes this now.  This however leads down
another interesting path.  We pass this pointer to bootm_load_os and
that in turn uses this uninitialized value immediately to calculate the
flush length, and is wrong.  We do not know what load_end will be until
after bootm_decomp_image is called, so we must only set flush_len after
that.  All of this also makes it clear that the only reason we pass a
pointer for load_end to bootm_load_os is so that we can call lmb_reserve
on success.  Rather than initialize load_end to 0 in do_bootm_states we
can just call lmb_reserve ourself.

find_next_zero_bit() incorrectly handles cases when:
- total bitmap size < 32
- rest of bits to process

static inline int find_next_zero_bit(void *addr, int size, int offset)
{
	unsigned long *p = ((unsigned long *)addr) + (offset >> 5);
	unsigned long result = offset & ~31UL;
	unsigned long tmp;

	if (offset >= size)
		return size;
	size -= result;
	offset &= 31UL;
	if (offset) {
		tmp = *(p++);
		tmp |= ~0UL >> (32-offset);
		if (size < 32)
[1]
			goto found_first;
		if (~tmp)
			goto found_middle;
		size -= 32;
		result += 32;
	}
	while (size & ~31UL) {
		tmp = *(p++);
		if (~tmp)
			goto found_middle;
		result += 32;
		size -= 32;
	}
[2]
	if (!size)
		return result;
	tmp = *p;

found_first:
[3]  tmp |= ~0UL >> size;

^^^ algo can reach above line from from points:
 [1] offset > 0 and size < 32, tmp[offset-1..0] bits set to 1
 [2] size < 32 - rest of bits to process
 in both cases bits to search are tmp[size-1..0], but line [3] will simply
 set all tmp[31-size..0] bits to 1 and ffz(tmp) below will fail.

example: bitmap size = 16, offset = 0, bitmap is empty.
 code will go through the point [2], tmp = 0x0
 after line [3] => tmp = 0xFFFF and ffz(tmp) will return 16.

found_middle:
	return result + ffz(tmp);
}

Fix it by correctly seting tmp[31..size] bits to 1 in the above case [3].
