octeontx2-af: cn10k: mcs: Fix a resource leak in the probe and remove functions

[ Upstream commit 87c978123ef1f346d7385eaccc141022d368166f ]

In mcs_register_interrupts(), a call to request_irq() is not balanced by a
corresponding free_irq(), neither in the error handling path, nor in the
remove function.

Add the missing calls.
