[glib: 7/30] gdbusconnection: Drop unnecessary volatile qualifiers from variables

[Philip Withnall <pwithnall src gnome org>]

commit 33612404397f87f0cd45da90d3aa9ab60df895ee

    gdbusconnection: Drop unnecessary volatile qualifiers from variables
    
    This should introduce no API changes; there are public functions
    exported by `GDBusConnection` which still have some (incorrectly)
    `volatile` arguments, but dropping those qualifiers would be an API
    break.
