Jacob Dahl eb40eed248 arch/arm/src/imxrt: Unify FlexCAN TX work and add SIOCGCANERRORS.
TX-complete and the deadline watchdog each queued their own callback on
the same work_s, and work_queue() cancels whatever is pending when a
work_s is reused, so whichever ran second was dropped: deadlines were
left set, the TX interrupt mask stayed off, or expired frames were never
aborted. Both now queue imxrt_tx_work(), which retires completions
before it aborts expired mailboxes.

Add SIOCGCANERRORS so a socket can read fault confinement, TEC/REC, a
monotonic bus error count and the RX mailbox overrun count. SIOCGCANSTATE
reports sleep/operational, not fault confinement, hence a new command.
The error count is sampled from the clear-on-read ESR1 error flags at
every driver entry rather than from ERRINT, which fires per error frame
and storms at bus rate once the bus is dead. Frames the CAN socket layer
drops for want of an IOB now count as rx_dropped in the netdev
statistics as well as in the global CAN statistics.

Tested on an i.MX RT1176 (ARK FMU-v6XRT) running PX4 with two DroneCAN
nodes: unplugging one node the ioctl reports error-passive, TEC 128,
REC 0 and a monotonic error count, matching ECR/ESR1 read over SWD at
20 Hz, while the other interface stays error-active with zero errors.
