7c56c393ba bit_array: return UINT32_MAX if no cleared bits found
spdk_bit_array_find_first_set() returns UINT32_MAX if no
set bits are found.  But spdk_bit_array_find_first_clear()
would return the size of the bit array instead in this case.
(Note: the comments say size of the bit array + 1 which was
incorrect)

So this patch makes spdk_bit_array_find_first_clear()
consistent with spdk_bit_array_find_first_set() and returns
UINT32_MAX if no cleared bit is found.

9d524f5353 bit_array: annotate bounds check as unlikely
The out-of-bounds case in the bit array accessors should not happen
normally, so help the compiler order the basic blocks correctly so that
the in-bounds case is the fallthrough path.
