bnxt: do not busy-poll when link is down
When busy polling while a link is down (during a link-flap test), TX
timeouts were observed as well as the following messages in the ring
buffer:
bnxt_en 0008:01:00.2 enP8p1s0f2d2: Resp cmpl intr err msg: 0x51
bnxt_en 0008:01:00.2 enP8p1s0f2d2: hwrm_ring_free tx failed. rc:-1
bnxt_en 0008:01:00.2 enP8p1s0f2d2: Resp cmpl intr err msg: 0x51
bnxt_en 0008:01:00.2 enP8p1s0f2d2: hwrm_ring_free rx failed. rc:-1
These were resolved by checking for link status and returning if link
was not up.
