cifs: move "ntlmssp" and "local_leases" options out of experimental code
I see no real need to leave these sorts of options under an EXPERIMENTAL ifdef. Since you need a mount option to turn this code on, that only blows out the testing matrix. local_leases has been under the EXPERIMENTAL tag for some time, but it's only the mount option that's under this label. Move it out from under this tag. The NTLMSSP code is also under EXPERIMENTAL, but it needs a mount option to turn it on, and in the future any distro will reasonably want this enabled. Go ahead and move it out from under the EXPERIMENTAL tag.
