[PATCH] lib/test_vmalloc.c: Add a new 'nr_pages' parameter

[Uladzislau Rezki (Sony)]

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.
