Shutdown only if CLOSE has been set to xprt->xp_flags

[rojingeorge]

This commit fixes a Hung issue, when we try to mount using NFSv3.

FDs getting shutdown/closed was causing issues post rearming the events...This got opened up as part of the changes made in 16daff0c1999c158dec9ad026902401b8ea7a64f...Old check put was removed in this patch...If the above changes were reverted, then all works fine...
