bitops: protect find_first_{,zero}_bit properly

bitops: protect find_first_{,zero}_bit properly

Patch series "Resend bitmap patches".

This patch (of 17):

find_first_bit() and find_first_zero_bit() are not protected with ifdefs
as other functions in find.h.  It causes build errors on some platforms if
CONFIG_GENERIC_FIND_FIRST_BIT is enabled.
