[2/3] gdb/cli: Remove casts of NULL during assignment.
Commit Message
In the following code:
struct symbol *wsym = (struct symbol *) NULL;
the cast of NULL is redundant, it adds noise, and is just one more thing
to change if the type of wsym ever changes. There are a relatively
small number of places in gdb where the above code pattern is used.
Usually the cast is removed like this:
struct symbol *wsym = NULL;
This commit updates all the places within the gdb/cli directory where we
cast NULL during assignment, removing the cast.

* cli/cli-decode.c (find_cmd): Remove cast of NULL pointer.
