Subject: arm32 build warnings in workqueue.c

Not sure what changed (maybe I ended up with -Werror on recently), but
my 32-bit arm build started to fail. 6.4.0-rc7.

gcc version 13.1.1 20230519 (Red Hat Cross 13.1.1-2) (GCC)

function ‘get_work_pwq’:

Just a drive-by, I'll disable Werror on my 32-bit arm build for now.

Dave.
