dpaa2-switch: Fix interrupt storm after receiving bad if_id in IRQ handler

In the Linux kernel, the following vulnerability has been resolved:

dpaa2-switch: Fix interrupt storm after receiving bad if_id in IRQ handler

Commit 31a7a0bbeb00 ("dpaa2-switch: add bounds check for if_id in IRQ
handler") introduces a range check for if_id to avoid an out-of-bounds
access. If an out-of-bounds if_id is detected, the interrupt status is
not cleared. This may result in an interrupt storm.

Clear the interrupt status after detecting an out-of-bounds if_id to avoid
the problem.
