ALSA: ali5451: remove irq enabling in pointer callback
commit dacae5a19b4cbe1b5e3a86de23ea74cbe9ec9652 upstream. snd_ali_pointer function is called with local interrupts disabled. However it seems very strange to reenable them in such way. Found by Linux Driver Verification project (linuxtesting.org).
