Subject: [PATCH 4.19 16/93] usb: gadget: composite: Clear "suspended" on reset/disconnect

[ Upstream commit 602fda17c7356bb7ae98467d93549057481d11dd ]

In some cases, one can get out of suspend with a reset or
a disconnect followed by a reconnect. Previously we would
leave a stale suspended flag set.
