Windows: Ensure that cm_NameI errors are acted upon promptly

Windows: Ensure that cm_NameI errors are acted upon promptly

There are many cases in the SMB server where an error from cm_NameI()
was either ignored or not acted upon until several other operations
are performed that could result in the same error being repeated.
This is a mistake which did not have negative side effects until
additional checks for callback status were added recently.

At present, if a CM_ERROR_ACCESS error is returned and ignored,
subsequent attempts to operate on the same cm_scache_t will result
in additional queries to the file server that will also end in an
abort response.  This can trigger the file server to delay responses
to the client.

This patchset ensures that all cm_NameI() errors are acted upon
promptly.
