[PATCH 5.19 0064/1157] parisc: Drop pa_swapper_pg_lock spinlock

From: Helge Deller <deller@gmx.de>

commit 3fbc9a7de0564c55d8a9584c9cd2c9dfe6bd6d43 upstream.

This spinlock was dropped with commit b7795074a046 ("parisc: Optimize
per-pagetable spinlocks") in kernel v5.12.

Remove it to silence a sparse warning.
