The existing vma_merge() function is no longer required to handle what
were previously referred to as cases 1-3 (i.e. the merging of a new VMA),
as this is now handled by vma_merge_new_vma().
Additionally, simplify the convoluted control flow of the original,
maintaining identical logic only expressed more clearly and doing away
with a complicated set of cases, rather logically examining each possible
outcome - merging of both the previous and subsequent VMA, merging of the
previous VMA and merging of the subsequent VMA alone.
We now utilise the previously implemented commit_merge() function to share
logic with vma_expand() de-duplicating code and providing less surface
area for bugs and confusion. In order to do so, we adjust this function
to accept parameters specific to merging existing ranges.
