[PATCH] usb: misc: usbsevseg: replace deprecated simple_strtoul with kstrtouint

[Jad Keskes]

simple_strtoul() is deprecated. kstrtouint() actually tells you when
the input is garbage instead of silently accepting zero.

Fixes 3 sysfs store paths (powered, mode_msb, mode_lsb) from one
macro expansion.
