dpaa2-switch: add bounds check for if_id in IRQ handler
The IRQ handler extracts if_id from the upper 16 bits of the hardware
status register and uses it to index into ethsw->ports[] without
validation. Since if_id can be any 16-bit value (0-65535) but the ports
array is only allocated with sw_attr.num_ifs elements, this can lead to
an out-of-bounds read potentially.
Add a bounds check before accessing the array, consistent with the
existing validation in dpaa2_switch_rx().
