* procfs.c (procfs_do_thread_registers): Added a call to fetch
	register values before saving them in the core file
	through the gcore command.
	(procfs_corefile_thread_callback): Removed the backup of
	inferior_ptid before calling procfs_do_thread_registers since
	the function already saves and restores it before returning.
