Fix erc-notifications-notify for non-PRIVMSGs, broken in last commit

* lisp/erc/erc-desktop-notifications.el (erc-notifications-notify):
Take optional argument `privp', to be non-nil when notifying for a
PRIVMSG.  This is to work around bug introduced in last commit, as
`erc-get-buffer' may return nil for non-PRIVMSG cases.
(erc-notifications-PRIVMSG): Call erc-notifications-notify with
non-nil `privp', as described above.
