smbfs: move to drivers/staging

smbfs has been scheduled for removal in 2.6.27, so
maybe we can now move it to drivers/staging on the
way out.

smbfs still uses the big kernel lock and nobody
is going to fix that, so we should be getting
rid of it soon.

This removes the 32 bit compat mount and ioctl
handling code, which is implemented in common fs
code, and moves all smbfs related files into
drivers/staging/smbfs.

+smbfs is on its way out of the kernel, it has been replaced
+by cifs several years ago.

+The smbfs code uses the big kernel lock which
+is getting deprecated.

+Users that find smbfs to work but not cifs should contact
+the CIFS developers on linux-cifs@vger.kernel.org.
