maple_tree: remove unused mas_is_root_limits()

Browse Source 
The last callers of mas_is_root_limits() were removed by commit
b8852ef30c ("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.
