[PATCH 1/2] staging: dgnc: use schedule_timeout_interruptible()

[Nicholas Mc Guire]

API consolidation with coccinelle found:
./drivers/staging/dgnc/dgnc_utils.c:16:1-17:
        consolidation with schedule_timeout_*() recommended

This is a 1:1 conversion with respect to schedule_timeout() to the
schedule_timeout_interruptible() helper only - so only an API
consolidation to improve readability. The timeout was being passed
as (ms * HZ) / 1000 but that is not reliable as it allows the timeout
to become 0 for small values of ms. As this cut-off is HZ dependent
this is most likely not intended, so the timeout is converted with 
msecs_to_jiffies which handles all corener-cases correctly.

Patch was compile tested with x86_64_defconfig + CONFIG_STAGING=y,
CONFIG_DGNC=m

Patch is against 4.1-rc5 (localversion-next is -next-20150529)
