[PATCH v2 4/6] drivers: hv: vmbus: Fix checkpatch SPLIT_STRING

[Matheus Castello]

Checkpatch emits WARNING: quoted string split across lines.
To keep the code clean and with the 80 column length indentation the
check and registration code for kmsg_dump_register has been transferred
to a new function hv_kmsg_dump_register.
