cifs: Optimize CIFSFindFirst() response when not searching

Browse Source 
When not searching for child entries with msearch wildcard pattern then ask
server just for one output entry. There is no need to ask for more entries
as we are interested only for one search result, as we are doing query on
path.

CIFSFindFirst() with msearch=false is called by the cifs_query_path_info()
function.
