Subject: [PATCH] staging: rtl8188eu: use msecs_to_jiffies for conversions

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

Signed-off-by: Nicholas Mc Guire <der.herr@...r.at>
---

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_R8188EU=m

Patch is against 3.19.0-rc6 -next-20150129
