Fix the following sparse context imbalance regression introduced in
a patch that fixed sleeping function called from invalid context bug.
kbuild test robot reported on:
tree/branch: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-linus
Regressions in current branch:
drivers/usb/usbip/stub_dev.c:399:9: sparse: sparse: context imbalance in 'stub_probe' - different lock contexts for basic block
drivers/usb/usbip/stub_dev.c:418:13: sparse: sparse: context imbalance in 'stub_disconnect' - different lock contexts for basic block
drivers/usb/usbip/stub_dev.c:464:1-10: second lock on line 476

This is a real problem in an error leg where spin_lock() is called on an
already held lock.
Fix the imbalance in stub_probe() and stub_disconnect().
