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.
