[PATCH] remove name length check in a workqueue

We have a chek in there to make sure that the name won't overflow
task_struct.comm[], but it's triggering for scsi with lots of HBAs, only
scsi is using single-threaded workqueues which don't append the "/%d"
anyway.

All too hard.  Just kill the BUG_ON.

[ kthread_create() uses vsnprintf() and limits the thing, so no
  actual overflow can actually happen regardless ]
