[gvdb: 1/2] Fix size of preallocated array

    Fix size of preallocated array
    
    Commit 084e1d868 added a preallocation to an array to avoid
    reallocations later on, but neglected the fact that after N insertions
    into the array, there’s always a NULL terminator added to the end. Fix
    the preallocation to include that NULL terminator.
    
    This doesn’t change the correctness of the code, but should eliminate
    one reallocation.
