smackfs: remove redundant lock, fix open(,O_RDWR)
Older smackfs was parsing MAC rules by characters, thus a need of locking
write sessions on open() was needed. This lock is no longer useful now since
each rule is handled by a single write() call.
This is also a bugfix since seq_open() was not called if an open() O_RDWR flag
was given, leading to a seq_read() without an initialized seq_file, thus an
Oops.
