ext4: stop looping in ext4_num_dirty_pages when max_pages reached
Today we simply break out of the inner loop when we have accumulated
max_pages; this keeps scanning forwad and doing pagevec_lookup_tag()
in the while (!done) loop, this does potentially a lot of work
with no net effect.
When we have accumulated max_pages, just clean up and return.
