SOLARIS: Support VSW_STATS

Specify the VSW_STATS flag to the vfsdef_t structure we give to
Solaris. This turns on statistics that can be retrieved via fsstat(1M)
and allows the fsinfo::: DTrace provider to work with AFS files.

We don't need to actually maintain these statistics; Solaris does that
for us. This flag just signifies that our vfs_t structure is capable
of storing the information. Since we get our vfs_t from Solaris (via
domount(), it gives us a vfs_t when it calls our afs_mount function)
and do not allocate a vfs_t ourselves, we are safe and this is fine to
do.
