[PATCH 5.15 174/913] xtensa: fix xtensa_wsr always writing 0

[Greg Kroah-Hartman]

From: Max Filippov <jcmvbkbc@xxxxxxxxx>

commit a3d0245c58f962ee99d4440ea0eaf45fb7f5a5cc upstream.

The commit cad6fade6e78 ("xtensa: clean up WSR*/RSR*/get_sr/set_sr")
replaced 'WSR' macro in the function xtensa_wsr with 'xtensa_set_sr',
but variable 'v' in the xtensa_set_sr body shadowed the argument 'v'
passed to it, resulting in wrong value written to debug registers.

Fix that by removing intermediate variable from the xtensa_set_sr
macro body.
