Subject: [PATCH] smb311: remove dead code for non compounded posix query info
Git-commit: e0ae8a9aaeed7262f349e025b2162e8a13cb58d9
Patch-mainline: v5.14-rc1
References: bsc#1192606

Although we may need this in some cases in the future, remove the
currently unused, non-compounded version of POSIX query info,
SMB11_posix_query_info (instead smb311_posix_query_path_info is now
called e.g. when revalidating dentries or retrieving info for getattr)
