Akinobu Mita 69b195be51 bfs: fix bitmap size argument to find_first_zero_bit() ...

The usage of find_first_zero_bit() in bfs_create() is wrong for two
reasons.

The bitmap size argument to find_first_zero_bit() is info->si_lasti but
the correct bitmap size is info->si_lasti + 1 as info->si_lasti is the
last valid index in info->si_imap bitmap.

Another problem is that it is impossible to detect that info->si_imap
bitmap is full because there is an off-by-one bug in the return value
check for find_first_zero_bit().  If no zero bits exist in info->si_imap,
find_first_zero_bit() returns info->si_lasti.  But the check can't catch
it due to the off-by-one.
