Subject: [PATCH v2] usbip: vudc: Make use of the helper macro LIST_HEAD()

Replace "struct list_head head = LIST_HEAD_INIT(head)" with
"LIST_HEAD(head)" to simplify the code.

LIST_HEAD() helps to clean up the code "struct list_head vudc_devices =",
only to care about the variable 'vudc_devices'.

v1->v2: update the changelog to explain why this change simplifies the code.
