net: kalmia: fix memory leaks
[ Upstream commit f1472cb09f11ddb41d4be84f0650835cb65a9073 ]
In kalmia_init_and_get_ethernet_addr(), 'usb_buf' is allocated through
kmalloc(). In the following execution, if the 'status' returned by
kalmia_send_init_packet() is not 0, 'usb_buf' is not deallocated, leading
to memory leaks. To fix this issue, add the 'out' label to free 'usb_buf'.
