staging: comedi: gsc_hpdi: usleep_range is preferred over udelay
Fix checkpatch issue: "CHECK: usleep_range is preferred over udelay; see
Documentation/timers/timers-howto.txt". `udelay()` is only called once
from a place where sleeping is allowed. Replace it with a call to
`usleep_range()` with a reasonable upper limit.
