In case we have I/O and try to remove an L2ARC device a deadlock might occur. arc_read()->zio_read()->zfs_blkptr_verify() waits for SCL_VDEV to be dropped while holding the hash_lock. However, spa_l2cache_load() holds SCL_ALL and waits for the hash_lock in l2arc_evict(). Fix this by moving zfs_blkptr_verify() to the top top arc_read() before the hash_lock is taken. Verify the block pointer and return a checksum error if damaged rather than halting the system, by using BLK_VERIFY_LOG instead of BLK_VERIFY_HALT.
