Bluetooth: btmtk: Do not discard the subsystem reset timeout

When the MTK_BT_RST_DONE poll times out, btmtk_usb_subsys_reset() logs
"Reset timeout" and keeps the error in err, but err is then overwritten
by the return value of the following btmtk_usb_id_get() call, so the
timeout is never reported to the caller.

Commit 25b6d7593a3a ("Bluetooth: btmtk: introduce btmtk reset work")
discarded the return value of the chip id read, so the function returned
the timeout error as intended. Commit 3dcb122b3064 ("Bluetooth: btusb:
mediatek: return error for failed reg access") started assigning err at
that call and silently dropped it.

Keep the timeout in a separate variable and return it, restoring the
original behaviour without changing the control flow.
