drm/tiny: correctly print `struct resource *` on error

The `res` variable is already a `struct resource *`, don't take the address of it.

Fixes incorrect output:

	simple-framebuffer 9e20dc000.framebuffer: [drm] *ERROR* could not acquire memory range [??? 0xffff4be88a387d00-0xfffffefffde0a240 flags 0x0]: -16

To be correct:

	simple-framebuffer 9e20dc000.framebuffer: [drm] *ERROR* could not acquire memory range [mem 0x9e20dc000-0x9e307bfff flags 0x200]: -16
