e1000e: Avoid wrong check on TX hang
commit 09357b00255c233705b1cf6d76a8d147340545b8 upstream.
Based on the original patch submitted my Michael Wang
<wangyun@linux.vnet.ibm.com>.
Descriptors may not be write-back while checking TX hang with flag
FLAG2_DMA_BURST on.
So when we detect hang, we just flush the descriptor and detect
again for once.
-v2 change 1 to true and 0 to false and remove extra ()
