[commit/obvious] Add "volatile" keyword to "struct gdb_exception" declaration

[Sergio Durigan Junior <sergiodj@redhat.com>]

Hi,

This patch adds the "volatile" keyword to the declaration of "struct
gdb_exception" in two places that were missing it.

Checked in as obvious.

    Add "volatile" keyword to "struct gdb_exception" declaration
    
    While doing something else, I found that those 2 places were incorrectly
    declaring a "struct gdb_exception" without using the "volatile" keyword.
    This commit fixes that.

    	* breakpoint.c (insert_bp_location): Add "volatile" keyword to "struct
    	gdb_exception" declaration.
    	* remote.c (getpkt_or_notif_sane): Likewise.
