[Qemu-devel] [PULL 05/22] dump: const-qualify the buf of WriteCoreDumpFunction

[Luiz Capitulino <lcapitulino@redhat.com>]

From: qiaonuohan <qiaonuohan@cn.fujitsu.com>

WriteCoreDumpFunction is a function pointer that points to the function used to
write content in "buf" into core file, so "buf" should be const-qualify.
