net: can: j1939: recover socket queue on CAN bus error during BAM transmission

Addresses an issue where a CAN bus error during a BAM transmission
could stall the socket queue, preventing further transmissions even
after the bus error is resolved. The fix activates the next queued
session after the error recovery, allowing communication to continue.
