Subject: HID: hyperv: fix possible memory leak in mousevsc_probe()
Git-commit: b5bcb94b0954a026bbd671741fdb00e7141f9c91
References: git-fixes
If hid_add_device() returns error, it should call hid_destroy_device()
to free hid_dev which is allocated in hid_allocate_device().
Fixes: 74c4fb058083 ("HID: hv_mouse: Properly add the hid device")
