more cleanup from recent patches.  comment out the recycling code because
it is not possible to implement it using the current locking hierarchy.

change cm_BufWrite to take a pointer to cm_scache_t instead of a fid
which must be used to look up a new reference to the cm_scache_t.
more often than not we already have the scp and in the one case we
don't we can let the caller look up the scp and then call cm_BufWrite
if it is found.  If not, we have saved a function call and a bunch
of lock operations.

add a lot more logging.

improve the scp mutex handling within smb_CloseFID
