[PATCH v2 3/5] misc/pvpanic-mmio: Fix error handling in 'pvpanic_mmio_probe()'

[Christophe JAILLET]

There is no error handling path in the probe function.
Switch to managed resource so that errors in the probe are handled easily
and simplify the remove function accordingly.

Fixes: b3c0f8774668 ("misc/pvpanic: probe multiple instances")
