[Hurd] Fix deallocation after proc_getprocinfo call

Browse Source 
2014-11-24  Samuel Thibault  <samuel.thibault@ens-lyon.org>

	* gdb/gnu-nat.c (inf_validate_procinfo): Multiply the number of
	elements pi_len by the size of the elements before calling
	vm_deallocate.
	(inf_validate_task_sc): Likewise, and properly deallocate the
	noise array.
