qlogic: qlcnic: fix use of SPEED_UNKNOWN ethtool constant
qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant,
which is defined as -1, resulting in value truncation and
thus incorrect test results against SPEED_UNKNOWN.
For example, the following test will print "False":
u16 speed = SPEED_UNKNOWN;
if (speed == SPEED_UNKNOWN)
printf("True");
else
printf("False");
Change storage of speed to use u32 to avoid this issue.
