tlan: Fix bugs introduced by the last tlan cleanup patch

Fix two bugs introduced by the commit
c659c38b ("tlan: Code cleanup:
checkpatch.pl is relatively happy now.") In that change,
TLAN_CSTAT_READY was considered as a bit mask containing a single bit
set while it was actually had two set instead.

Many thanks to Dan Carpenter for finding the mistake.
