[PATCH] ide_tape: convert jiffies with jiffies_to_msecs

[Nicholas Mc Guire]

Use jiffies_to_msecs for converting jiffies as it handles all of the corner
cases reliably and also helps readability. The printk format is fixed up 
as jiffies_to_msecs returns unsigned int not unsigned long.

Note that this patch will give a checkpatch warning due to "quoted string 
split across lines" but thats not related to this change - not sure if this
should be fixed - looks intentional to me.

This was only compile tested with x86_64_defconfig + CONFIG_IDE=m,
CONFIG_BLK_DEV_IDETAPE=m

Patch is against 4.0-rc1 (localversion-next is -next-20150303)
