[libvirt] [PATCH] doc: Correct the default werror policy

[Osier Yang]

<quote>
@item werror=@var{action},rerror=@var{action}
Specify which @var{action} to take on write and read errors. Valid actions are:
"ignore" (ignore the error and try to continue), "stop" (pause QEMU),
"report" (report the error to the guest), "enospc" (pause QEMU only if the
host disk is full; report the error to the guest otherwise).
The default setting is @option{werror=enospc} and @option{rerror=report}.
@item readonly

libvirt doesn't set any default value for "(r)error_policy", the
original doc should mean QEMU sets "report" as the default value
for "werror", but it's not true, QEMU uses "enospc" as the default.
And it's better to document "(r)error_policy" are only supported
by QEMU.
