usb: gadget: f_hid: fix report descriptor allocation
commit 61890dc2 upstream. The commit 89ff3dfa ("usb: gadget: f_hid: fix f_hidg lifetime vs cdev") has introduced a bug that leads to hid device corruption after the replug operation. Reverse device managed memory allocation for the report descriptor to fix the issue. Tested: This change was tested on the AMD EthanolX CRB server with the BMC based on the OpenBMC distribution. The BMC provides KVM functionality via the USB gadget device: - before: KVM page refresh results in a broken USB device, - after: KVM page refresh works without any issues.
