Bluetooth: btusb: Fix not handling ZPL/short-transfer

[ Upstream commit 7b05933340f4490ef5b09e84d644d12484b05fdf ] Requesting transfers of the exact same size of wMaxPacketSize may result in ZPL/short-transfer since the USB stack cannot handle it as we are limiting the buffer size to be the same as wMaxPacketSize. Also, in terms of throughput this change has the same effect to interrupt endpoint as 290ba200815f "Bluetooth: Improve USB driver throughput by increasing the frame size" had for the bulk endpoint, so users of the advertisement bearer (e.g. BT Mesh) may benefit from this change.

Bluetooth: qca: Fix BT enable failure again for QCA6390 after warm reboot

commit 88e72239ead9814b886db54fc4ee39ef3c2b8f26 upstream. Commit 272970be3dab ("Bluetooth: hci_qca: Fix driver shutdown on closed serdev") will cause below regression issue: BT can't be enabled after below steps: cold boot -> enable BT -> disable BT -> warm reboot -> BT enable failure if property enable-gpios is not configured within DT|ACPI for QCA6390. The commit is to fix a use-after-free issue within qca_serdev_shutdown() by adding condition to avoid the serdev is flushed or wrote after closed but also introduces this regression issue regarding above steps since the VSC is not sent to reset controller during warm reboot. Fixed by sending the VSC to reset controller within qca_serdev_shutdown() once BT was ever enabled, and the use-after-free issue is also fixed by this change since the serdev is still opened before it is flushed or wrote.
