[PATCH v2] system/runstate.c: Add a newline character to correctly log guest errors

[xpahos@gmail.com]

From: Alexander Gryanko <xpahos@gmail.com>

The pvpanic handler calls the qemu_system_guest_panicked
function with a NULL parameter, which results in the absence
of a newline character in the guest error log.
The qemu_system_guest_crashloaded function has no additional
logic, but also omits the newline character.
The qemu_system_guest_pvshutdown has no reporting in the
guest error log.
