setrlimit/getrlimit: Use __nonnull to avoid null pointer
Add __nonnull((2)) to the setrlimit()/getrlimit() function declaration
to avoid null pointer access.
-----
v2
According to the suggestions of the Adhemerval Zanella and Zack Weinberg:
use __nonnull() to check null pointers in the compilation phase.
do not add pointer check code to setrlimit()/getrlimit().
The validity of the "resource" parameter is checked in the syscall.
