Subject: [PATCH v7 1/3] staging: vt6655: fix camelcase in bShortSlotTime

Replace camel case variable bShortSlotTime with snake case variable
short_slot_time. bShortSlotTime is a boolean variable, if true short
slot time is enabled, false not. Short Slot Time reduces the slot time
from 20 microseconds to 9 microseconds, where the slot time is
the maximum theoretical time for a frame to travel a network.
