[PATCH] Fix use of uninitialized value in linux-arm-low in GDBServer.

[Antoine Tremblay <antoine.tremblay@ericsson.com>]

In arm_breakpoint_at, an uninitialized unsigned long was used were only
4 bytes would be written to the variable thus polluting the value on 64bit.

This patch changes the value to an unsigned int.
