fb: fix fb_pan_display range check
Fix the range check for panning. The current code fails to detect some
invalid values (very high ones that can occur if an app tries to move
further up/left than 0,0) as the check uses the unknown values for
calculation so that an overflow can occur.
To fix this it is sufficient to move the calculation to the right side to
use only trusted values.
Kai Jiang detected this problem and proposed an initial patch.
