can: c_can: fix segfault during rmmod
This patch fixes an oops which occurs during unloading the driver.
unregister_c_can_dev() is doing c_can/d_can module interrupts disable, which
requires module clock enable. c_can/d_can interrupts enable/disable is handled
properly in c_can_start and c_can_stop, so removing from
unregister_c_can_dev().
The problem was triggered by adding runtime PM support to the c_can driver by
this commit:
