Subject: [PATCH] staging: lustre: Fix an error handling path in 'client_common_fill_super()'

According to error handling path before and after this one, we should go
to 'out_md_fid' here, instead of 'out_md', if 'obd_connect()' fails.

The last goto 'out_lock_cn_cb' looks spurious but is correct.
In case of error, 'd_make_root()' performs a 'iput()', so skipping it in
the error handling path lokks fine to me.
