cifs: Add new parameter "acregmax" for distinct file and directory metadata timeout
The new optional mount parameter "acregmax" allows a different timeout for file metadata ("acdirmax" now allows controlling timeout for directory metadata). Setting "actimeo" still works as before, and changes timeout for both files and directories, but specifying "acregmax" or "acdirmax" allows overriding the default more granularly which can be a big performance benefit on some workloads. "acregmax" is already used by NFS as a mount parameter (albeit with a larger default and thus looser caching).
