fs/ntfs3: add prefix to bitmap_size() and use BITS_TO_U64()
bitmap_size() is a pretty generic name and one may want to use it for
a generic bitmap API function. At the same time, its logic is
NTFS-specific, as it aligns to the sizeof(u64), not the sizeof(long)
(although it uses ideologically right ALIGN() instead of division).
Add the prefix 'ntfs3_' used for that FS (not just 'ntfs_' to not mix
it with the legacy module) and use generic BITS_TO_U64() while at it.
