usbc: fix storm tracker overflow issue
If there is no USB-C interrupt activity for 2^31 microseconds, then
there are more than ALERT_STORM_MAX_COUNT events within 2^31
microsecond (instead of ALERT_STORM_INTERVAL), then the interrupt
storm would incorrectly detect a storm and disable the port due
to incorrect math regarding 32-bit overflow.
(Needed to remove tests for cherry-pick to branch)
BRANCH=octopus and all branches with original storm detection
(CL:1650484)
BUG=b:144369187
TEST=unit test in CL
