Somnath Kotur 320dcbdec4 bnxt_en: Check abort error state in bnxt_half_open_nic() 
[ Upstream commit 11a39259ff79b74bc99f8b7c44075a2d6d5e7ab1 ]

bnxt_half_open_nic() is called during during ethtool self test and is
protected by rtnl_lock.  Firmware reset can be happening at the same
time.  Only critical portions of the entire firmware reset sequence
are protected by the rtnl_lock.  It is possible that bnxt_half_open_nic()
can be called when the firmware reset sequence is aborting.  In that
case, bnxt_half_open_nic() needs to check if the ABORT_ERR flag is set
and abort if it is.  The ethtool self test will fail but the NIC will be
brought to a consistent IF_DOWN state.

Without this patch, if bnxt_half_open_nic() were to continue in this
error state, it may crash like this:

  bnxt_en 0000:82:00.1 enp130s0f1np1: FW reset in progress during close, FW reset will be aborted
  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
  ...
