Deduplicate the ocfs2 file type conversion implementation and remove
OCFS2_FT_* definitions - file systems that use the same file types
as defined by POSIX do not need to define their own versions and can
use the common helper functions decared in fs_types.h and implemented
in fs_types.c
Common implementation can be found via commit:
bbe7449e2599 "fs: common implementation of file type"
