NFSv4: pass lease period in seconds to nfs4_set_lease_period()

There's no need to multiply the lease period by HZ at all the call sites of
nfs4_set_lease_period() -- it makes more sense to do that only once, inside
that function, by passing to it lease period as 32-bit # of seconds instead
of 32/64-bit *unsigned long* # of jiffies...
