can: m_can: Release irq on error in m_can_open
It appears that the irq requested in m_can_open() may be leaked
if an error subsequently occurs: if m_can_start() fails.
Address this by calling free_irq in the unwind path for
such cases.
Flagged by Smatch.
Compile tested only.
Fixes: eaacfeaca7ad ("can: m_can: Call the RAM init directly from m_can_chip_config")
