can: mcp251x: fix endless loop in interrupt handler if CANINTF_MERRF is set

Browse source

Commit d3cd156575 introduced a bug, the
interrupt handler would loop endlessly if the CANINTF_MERRF bit is set,
because it's not cleared.

This patch fixes the problem by masking out the CANINTF_MERRF and all other
non interesting bits.
