LINUX: Use correct type of error in flock code

The flock code gets a kernel error code from afs_posix_lock_file()
but then passes this error code through afs_convert_code (which sees
that it is already negative, and returns EIO). Instead, we should just
return afs_posix_lock_file()'s code direct to our caller.
