[PATCH v2] e1000e: Assign true and false to bool type variable instead of 1 and 0

[Michael Wang <wangyun@linux.vnet.ibm.com>]

From: Michael Wang <wangyun@linux.vnet.ibm.com>

Use true and false instead of 1 and 0 when assign value to a bool type
variable.

This patch is try to keep the style of driver, and according to David's
suggestion on patch "e1000e: Avoid wrong check on TX hang":

v2: add more description
