ceph: reinitialize mds feature bit even when session in open

Browse Source 
[ Upstream commit f48e0342a74d7770cdf1d11894bdc3b6d989b29e ]

Following along the same lines as per the user-space fix. Right
now this isn't really an issue with the ceph kernel driver because
of the feature bit laginess, however, that can change over time
(when the new snaprealm info type is ported to the kernel driver)
and depending on the MDS version that's being upgraded can cause
message decoding issues - so, fix that early on.
