[PATCH v2 0/2] maple_tree: mas_wr_append() fix ups

[Liam R. Howlett]

There is a potential of an update causing issue with a reader when
appending, so disable the append operation when readers a present.

The code was also missing some documentation, tracing, and some cleanup
was possible.  These changes are in the second patch as there's no
compelling reason to require a difficult backport.

Changes since v1:
 - Added fixes tag to the first patch
