Tianyu Lan 94ebb1eea0 x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump 
[ Upstream commit 7f11a2cc10 ]

If kmsg_dump_register() fails, hv_panic_page will not be used
anywhere.  So free and reset it.

Fixes: 81b18bce48 ("Drivers: HV: Send one page worth of kmsg dump over Hyper-V during panic")
