[RFC][PATCH v5 03/09] hfsplus: use fs_umode_to_dtype() helper

[Phillip Potter <phil@philpotter.co.uk>]

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
