Subject: [PATCH] [ALSA] sound: rme32.c irq enabling after spin_lock_irq

According to the other code in this driver and similar
code in rme96 it seems, that spin_lock_irq in
snd_rme32_capture_close function should be paired
with spin_unlock_irq.

Found by Linux Driver Verification project (linuxtesting.org).
