optimization for BLI_array_growitems (better put - improve inefficient method), BLI_array_growone was being called in a loop, even if the size of the allocated array was big enough for all items.

In this case now just adjust the count value since theres no need to loop,
when the allocation is not big enough BLI_array_growone in a loop is still used though.
