Merge patch series "can: kvaser_pciefd: Fix ISR race conditions"

Axel Forsman <axfo@kvaser.com> says:

This patch series fixes a couple of race conditions in the
kvaser_pciefd driver surfaced by enabling MSI interrupts and the new
Kvaser PCIe 8xCAN.

Changes since version 2:
* Rebase onto linux-can/main to resolve del_timer()/timer_delete()
  merge conflict.
* Reword 2nd commit message slightly.

Changes since version 1:
* Change type of srb_cmd_reg from "__le32 __iomem *" to
  "void __iomem *".
* Maintain TX FIFO count in driver instead of querying HW.
* Stop queue at end of .start_xmit() if full.
