[PATCH] maple: change the pointer name from maple_enode to maple_enode_p

[Li Hongyu <lihongyu1999@bupt.edu.cn>]

The current name of the pointer to struct maple_enode is also
maple_enode. This is correct from the grammar point but can be
comfusing. Besides it seems in Linux it prefers typedef struct foo
*foo_p;, e.g. typedef struct cpumask *cpumask_var_t; and typedef
struct cgraph_node *cgraph_node_ptr;. I use re to search in the
Linux project and cannot find another example in typedef struct
foo *foo; style.

This also results in a bug in the bindings of the
rust-for-linux subsystem, which can be seen in this github issue.

https://github.com/Rust-for-Linux/linux/issues/795

The struct pointer maple_enode and maple_pnode are not used. It is
safe to change it to a new name.
