cifs: replace /proc/fs/cifs/Experimental with a module parm
This flag currently only affects whether we allow "zero-copy" writes with signing enabled. Typically we map pages in the pagecache directly into the write request. If signing is enabled however and the contents of the page change after the signature is calculated but before the write is sent then the signature will be wrong. Servers typically respond to this by closing down the socket. Still, this can provide a performance benefit so the "Experimental" flag was overloaded to allow this. That's really not a good place for this option however since it's not clear what that flag does. Move that flag instead to a new module parameter that better describes its purpose. That's also better since it can be set at module insertion time by configuring modprobe.d.
