[PATCH 2/7] can: m_can: Remove coalesing disable in isr during suspend

[Markus Schneider-Pargmann]

We don't need to disable coalescing when the interrupt handler executes
while the chip is suspended. The coalescing is already reset during
suspend.

Fixes: 07f25091ca02 ("can: m_can: Implement receive coalescing")
