net/9p/usbg: fix handling of the failed kzalloc() memory allocation
[ Upstream commit ff1060813d9347e8c45c8b8cff93a4dfdb6726ad ]
On the linux-next, next-20241108 vanilla kernel, the coccinelle tool gave the
following error report:
./net/9p/trans_usbg.c:912:5-11: ERROR: allocation function on line 911 returns
NULL not ERR_PTR on failure
kzalloc() failure is fixed to handle the NULL return case on the memory exhaustion.
Fixes: a3be076dc174d ("net/9p/usbg: Add new usb gadget function transport")
