f2fs: allow compression for mmap files in compress_mode=user

[ 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.
