Jeffy Chen 19cfe912c3 Bluetooth: btusb: Fix memory leak in play_deferred 
Currently we are calling usb_submit_urb directly to submit deferred tx
urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak:
unreferenced object 0xffffffc0ce0fa400 (size 256):
...
  backtrace:
    [<ffffffc00034a9a8>] __save_stack_trace+0x48/0x6c
    [<ffffffc00034b088>] create_object+0x138/0x254
    [<ffffffc0009d5504>] kmemleak_alloc+0x58/0x8c
    [<ffffffc000345f78>] __kmalloc+0x1d4/0x2a0
    [<ffffffc0006765bc>] usb_alloc_urb+0x30/0x60
    [<ffffffbffc128598>] alloc_ctrl_urb+0x38/0x120 [btusb]
    [<ffffffbffc129e7c>] btusb_send_frame+0x64/0xf8 [btusb]

Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.
