[igt-dev] [PATCH i-g-t] tests/vgem_basic: Fix unload testcase

[Daniel Vetter]

An mmap _should_ keep the module alive.

This reverts

    igt/vgem_basic: Allow mmap() to persist without the vgem module loaded

With real drivers there is usually more than just shmem around, so
encoding this as some kind of expectation just doesn't make sense at
all.
