Marc Kleine-Budde 4563588ce5 can: c_can: don't call pm_runtime_get_sync() from interrupt context

commit e35d46adc4 upstream.

The c_can driver contians a callpath (c_can_poll -> c_can_state_change ->
c_can_get_berr_counter) which may call pm_runtime_get_sync() from the IRQ
handler, which is not allowed and results in "BUG: scheduling while atomic".

This problem is fixed by introducing __c_can_get_berr_counter, which will not
call pm_runtime_get_sync().
