linux-6.3-rc6/lib/maple_tree.c: Two style issues

Hello there,

>It should be fine here. 

Perhaps I have been slightly less than clear. The discussion is about the *style*
of the code, *not* whether it works or not. My apologies for the lack of clarity. 

Expression is

    while (A &&
        B && C)

The static analyser notices it is poor style to have B do a limit check, but have A use it.
Sure its working code, but suggest new code

    while (B && A && C)

It won't make much difference to the code, it will merely be better style.

sizeof( pivs[ 0]) is a better thing to say than sizeof( unsigned long). 
There is reduced future maintenance burden, when the type of *pivs changes.
