[PATCH] ps3disk: Do not use dev->bounce_size before it is set

From: Geert Uytterhoeven
Date: Fri Jan 03 2025 - 03:59:00 EST


dev->bounce_size is only initialized after it is used to set the queue
limits. Fix this by using BOUNCE_SIZE instead.

Fixes: a7f18b74dbe17162 ("ps3disk: pass queue_limits to blk_mq_alloc_disk")
