If we error out at mmap_offset cr

Right now the DRM_PANTHOR_BO_NO_MMAP flag is ignored by
panthor_ioctl_bo_mmap_offset(), meaning BOs with this flag set can
have a file offset but can't be mapped anyway, because
panthor_gem_mmap() will filter them out.
If we error out at mmap_offset creation time, we can get rid of
panthor_gem_mma
