[PATCH 5.18 015/102] parisc/unaligned: Fix emulate_ldw() breakage

[Greg Kroah-Hartman]

From: Helge Deller <deller@xxxxxx>

commit 96b80fcd2705fc50ebe1f7f3ce204e861b3099ab upstream.

The commit e8aa7b17fe41 broke the 32-bit load-word unalignment exception
handler because it calculated the wrong amount of bits by which the value
should be shifted. This patch fixes it.
