tg3: Hold tp->lock before calling tg3_halt() from tg3_init_one()

tg3: Hold tp->lock before calling tg3_halt() from tg3_init_one()

[ Upstream commit d0af71a3573f1217b140c60b66f1a9b335fb058b ]

tg3_init_one() calls tg3_halt() without tp->lock despite its assumption
and causes deadlock.
If lockdep is enabled, a warning like this shows up before the stall:

  [ BUG: bad unlock balance detected! ]
  3.19.0test #3 Tainted: G            E
  -------------------------------------
  insmod/369 is trying to release lock (&(&tp->lock)->rlock) at:
  [<ffffffffa02d5a1d>] tg3_chip_reset+0x14d/0x780 [tg3]
  but there are no more locks to release!

tg3_init_one() doesn't call tg3_halt() under normal situation but
during kexec kdump I hit this problem.
