NFS: Ensure the NFS_CAP_SECURITY_LABEL capability is set when appropriate

Commit ce62b114bbad ("NFS: Split attribute support out from the server
capabilities") removed the logic from _nfs4_server_capabilities() that
sets the NFS_CAP_SECURITY_LABEL capability based on the presence of
FATTR4_WORD2_SECURITY_LABEL in the attr_bitmask of the server's response.
Now NFS_CAP_SECURITY_LABEL is never set, which breaks labelled NFS.

This was replaced with logic that clears the NFS_ATTR_FATTR_V4_SECURITY_LABEL
bit in the newly added fattr_valid field based on the absence of
FATTR4_WORD2_SECURITY_LABEL in the attr_bitmask of the server's response.
This essentially has no effect since there's nothing looks for that bit
in fattr_supported.

So revert that part of the commit, but adding the logic that sets
NFS_CAP_SECURITY_LABEL near where the other capabilities are set in
_nfs4_server_capabilities().
