[ Upstream commit 66d34fcbbe63ebd8584b792e0d741f6648100894 ]
Since commit e3c548323d32 ("f2fs: let's allow compression for mmap files"), it has been allowed to compress mmap files. However, in compress_mode=user, it is not allowed yet. To keep the same concept in both compress_modes, f2fs_ioc_(de)compress_file() should also allow it.
Let's remove checking mmap files in f2fs_ioc_(de)compress_file() so that the compression for mmap files is also allowed in compress_mode=user.
