[PATCH][next] can: kvaser_pciefd: remove redundant negative check on trigger

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The check to see if trigger is less than zero is always false, trigger
is always in the range 0..255.  Hence the check is redundant and can
be removed.

Addresses-Coverity: ("Logically dead code")
