[ros-diffs] [sginsberg] 42215: - Fix a critical bug in ExAllocatePoolWithQuota spotted by msvc. Because of the current POOL_TAGGING mess in wdm.h, ExAllocatePoolWithQuotaTag is defined to ExAllocatePoolWithQuota, so when ExAllocatePoolWithQuota called the with-tag version, it ended up calling _itself_. Fix this by undefining the broken macro.
