[PATCH 2/2] mm/mprotect: drop 'sub' from batching context

[Dev Jain <dev.jain@arm.com>]

Shorten the name of page_anon_exclusive_sub_batch by dropping the
"sub-batch" context - the function itself doesn't need this context.
Similarly, drop "sub" from sub_batch_idx, it is unnecessary and the
usage is clear enough.
