This is only an API consolidation to make things more readable.
Instances of  var * HZ / 1000  are replaced by  msecs_to_jiffies(var).

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
ok but msecs_to_jiffies(val) is the cleaner solution and handles all
corner cases correctly. This is a minor API cleanup only.

This patch was only compile tested with x86_64_defconfig + CONFIG_STAGING=y
CONFIG_UNISYSSPAR=y, CONFIG_UNISYS_VISORUTIL=m,
CONFIG_UNISYS_VISORCHANNEL=m, CONFIG_UNISYS_VISORCHIPSET=m 

Patch is against 3.19.0-rc6 -next-20150129
