ztest currently uses the boolean flag ztest_device_removal_active to protect some tests that may not run successfully if they occur at the same time as ztest_device_removal(). Unfortunately, in the event that ztest is in the middle of a device removal when it decides to issue a SIGKILL, the device removal will be automatically restarted (without setting the flag) when the pool is re-imported on the next run. This patch corrects this by ensuring that any in-progress removals are completed before running further tests after the re-import. This patch also makes a few small changes to prevent race conditions involving the creation and destruction of spa->spa_vdev_removal, since this field is not protected by any locks. Some checks that may run concurrently with setting / unsetting this field have been updated to check spa->spa_removing_phys.sr_state instead. The most significant change here is that spa_removal_get_stats() no longer accounts for in-flight work done, since that could result in a NULL pointer dereference.
