net: usb: r8152: fix resume reset deadlock

In the Linux kernel, the following vulnerability has been resolved:

net: usb: r8152: fix resume reset deadlock

rtl8152 can trigger device reset during reset which
potentially can result in a deadlock:

 **** DPM device timeout after 10 seconds; 15 seconds until panic ****
 Call Trace:
 <TASK>
 schedule+0x483/0x1370

 usb_resume_interface+0x3e/0xc0
 usb_resume_both+0x104/0x150
 usb_resume+0x22/0x110

The problem is that rtl8152 resume calls reset under
tp->control mutex while reset basically re-enters rtl8152
and attempts to acquire the same tp->control lock once
again.

Reset INACCESSIBLE device outside of tp->control mutex
scope to avoid recursive mutex_lock() deadlock.
