Alexandra DiupinaandGreg Kroah-Hartman ba3ce6c60c cifs: avoid NULL pointer dereference in dbg call 
[ Upstream commit b4885bd593 ]

cifs_server_dbg() implies server to be non-NULL so
move call under condition to avoid NULL pointer dereference.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: e79b0332ae ("cifs: ignore cached share root handle closing errors")
