Fix smb_FindFIDByScache() to avoid obtaining the smb_fid_t.mx and
smb_rctLock out of order.  Doing so requires obtaining references
on each smb_fid_t belonging to the smb_vc_t in order to prevent them
from being removed from the list while the list is being walked.

Reorder tests for CM_SCACHEFLAG_DELETED and smb_fid_t.scp to make
them more efficient and consistent.

When processing Tran2SetPathInfo do not fail because an smb_fid_t
cannot be found for the path object.  The PathInfo function is
being used because we do not have a file descriptor.  Most importantly
do not fail by returning success.
