[igt-dev] [PATCH i-g-t 1/2] i915/gem_mmap_offset: Check mapping availability

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

When we pass invalid handles to GEM_MMAP_OFFSET ioctl we should check
return error code only for supported mapping types. Use real handle
to verify kernel supports such mapping type.
