[PATCH 5/5] ASoC: SDCA: Tidy up irq_enable_flags()/sdca_irq_disable()

[Charles Keepax <ckeepax@opensource.cirrus.com>]

In irq_enable_flags() and sdca_irq_disable() there is a NULL
check on the interrupt data pointer, however this is just pulled
from an array so can never be NULL. This was likely left over
from an earlier version that looked up the data in a different
way. Replace the check with checking for the IRQ itself being
non-zero.

Whilst here also drop the sdca_interrupt structure down into
the loop within the function to better match the style of the
rest of the code in this file.
