[PATCH 6/8] md: get_disk_info(): Don't convert between signed and unsigned and back.

[Andre Noll <maan@xxxxxxxxxxxxxxx>]

The current code copies a signed int from user space, converts it to
unsigned and passes the unsigned value to find_rdev_nr() which expects
a signed value. Simply pass the signed value from user space directly.
