ASoC: sn95031: Avoiding spurious OC interrupts and reduction of delay in OC Interrupt handler

This patch masks the OCVOLSTSMASK bit of OCAUDIOMASK regsiter as soon as the
Over current interrupt is received by the audio driver and it unmasks the same
register after restoring the IHF volume.Also the delay to schedule the
delayed Over current workqueue has been reduced to 100msec from 1 sec.

This patch will fix audio driver from receiving the spurious Over Current
interrupts and also reduces the delay in the over current interrupt handler.
