David S. Miller c87fe1c05d sparc32: Kill none_mask, it's bogus. 
For some reason, the pte_none() calculation for srmmu sparc32
chips was masking out the top 4 bits.  That doesn't make any
sense, as those are just some of the physical bits of the PTE
encoding.

Furthermore, this mistake breaks things when the offset of of a swap
entry has a large enough offset as reported by Тхай Кирилл.

Sun4c always set it to zero, so it's really completely useless,
kill it.
