can: mcp25xxfd: mcp25xxfd_can_fifo_clear(): fix fifo initialization
By masking the FIFO number in the MCP25XXFD_CAN_FLTCON macro, the
mcp25xxfd_can_fifo_clear() function doesn't clear the filters at all, as
the masking makes MCP25XXFD_CAN_FLTCON(32) equal MCP25XXFD_CAN_FLTCON(0).
| mcp25xxfd_can_fifo_clear_regs(cpriv, MCP25XXFD_CAN_FLTCON(0),
| MCP25XXFD_CAN_FLTCON(32));
