PATCH v6 2/7 hfsplus: use fs_umode_to_dtype() helper

Replace if/else statements with common lookup table implementation - 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"
