lib/test_vmalloc.c: add a new 'nr_pages' parameter
In order to simulate different fixed sizes for vmalloc allocation introduce a new parameter that sets number of pages to be allocated for the "fix_size_alloc_test" test. By default 1 page is used unless a different number is specified over the new parameter.
