Fix rounding of minSteerSpeed in events (#1620)

I thought I was missing a rounding in Mazda code, but it turned
out to be a missing rounding after the recent event refactoring

Python3 interpreter:
>>> print(" %d  %d" % (1.6,1.4))
 1  1
>>> print(" %d  %d" % (round(1.6),round(1.4)))
 2  1
>>> print(" %d  %d" % (int(round(1.6)),round(1.4)))
 2  1
>>> print(" %d  %d" % (int(round(1.6)),int(round(1.4))))
 2  1
