[Qemu-devel] [PATCH v3 03/10] ipmi: remove IPMI_CHECK_RESERVATION() macro

["Cédric Le Goater" <clg@fr.ibm.com>]

Some IPMI command handlers in the BMC simulator use a macro
IPMI_CHECK_RESERVATION() to check a SDR reservation but the macro
implicitly uses local variables. This patch simply removes it.
