Subject: [PATCH] fs: nullfs should include mount.h

The nullfs_fs_type is declared in mount.h but when declared
in nullfs.c there is a warning as mount.h is not being
included.

Add include of "mount.h" to remove the following sparse warning:
fs/nullfs.c:66:25: warning: symbol 'nullfs_fs_type' was not declared. Should it be static?
