libf2fs: fix incorrect type define of declaration
libf2fs: fix incorrect type define of declaration

When compiling f2fs toolset in 32-bits machine, following error was
reported:

libf2fs.c:342:5: error: conflicting types for 'find_next_bit_le'
../include/f2fs_fs.h:864:22: note: previous declaration of 'find_next_bit_le' was here
libf2fs.c:348:5: error: conflicting types for 'find_next_zero_bit_le'
../include/f2fs_fs.h:865:22: note: previous declaration of 'find_next_zero_bit_le' was here

This is because our type of return value(u64 in define) and (unsigned long
in declaration) of find_next_{,zero_}bit_le were not same in non-64-bits
machine:

extern unsigned long find_next_bit_le(const u8 *, u64, u64);
u64 find_next_bit_le(const u8 *addr, u64 size, u64 offset)

Fix it.
