* [PATCH kvm-unit-tests] vmx: give more memory to VMX tests

VMX tests need to allocate 1G-aligned memory to set up a huge page.
However, with a 2 GiB guest there is exactly one such page, exactly at
top of memory.  Now that vmalloc now uses the page allocator, tests
fail; just give them more memory.

Fixes:

    FAIL: x86/vmx_tests.c:2616: Assertion failed: data->hva
            STACK: 407050 40922a 401e4d 403ac4 400312
