sunrpc: simplify rpcauth_cache_shrink_count()

It is inappropriate to use sysctl_vfs_cache_pressure here.
The sysctl is documented as: This percentage value controls
the tendency of the kernel to reclaim the memory which is used
for caching of directory and inode objects.

So, simplify result of rpcauth_cache_shrink_count() to
"return number_cred_unused;".
