Subject: lib/find_bit.c: uninline helper _find_next_bit()

It saves 25% of .text for arm64, and more for BE architectures.

Before:
$ size lib/find_bit.o
   text    data     bss     dec     hex filename
   1012      56       0    1068     42c lib/find_bit.o

After:
$ size lib/find_bit.o
   text    data     bss     dec     hex filename
    776      56       0     832     340 lib/find_bit.o
