Subject: [PATCH] f2fs: allows setting compress option to files which marked with FI_MMAP_FILE

Allow to compress mmap files in commit e3c548323d32 ("f2fs: let's
allow compression for mmap files"). However, we cannot set the
compress option to the mmap file. To keep the same concept in both
compress_modes, f2fs_ioc_set_compress_option should also allow it.

Let's remove checking mmap files in f2fs_ioc_set_compress_option so
that we can set compress option to the mmap files.
