can: mcp251xfd: mcp251xfd_probe(): fix an error pointer dereference in probe 

When we converted this code to use dev_err_probe() we accidentally
removed a return. It means that if devm_clk_get() it will lead to an
Oops when we call clk_get_rate() on the next line.

Fixes: cf8ee6de25 ("can: mcp251xfd: mcp251xfd_probe(): use dev_err_probe() to simplify error handling")
