[PATCH] maple_tree: Remove unused mas_is_root_limits()

[Zhan Xusheng]

The last callers of mas_is_root_limits() were removed by commit
b8852ef30c67 ("maple_tree: remove maple big node and subtree structs"),
together with the maple subtree state (mast_*) code that used it. As a
static inline it does not trigger -Wunused-function, so it went
unnoticed.

Remove it. No functional change.
