sched_ext: Make cast_mask() inline
cast_mask() doesn't do any actual work and is defined in a header file.
Force it to be inline. When it is not inlined and the function is not used,
it can cause verificaiton failures like the following:
# tools/testing/selftests/sched_ext/runner -t minimal
===== START =====
TEST: minimal
DESCRIPTION: Verify we can load a fully minimal scheduler
OUTPUT:
libbpf: prog 'cast_mask': missing BPF prog type, check ELF section name '.text'
libbpf: prog 'cast_mask': failed to load: -22
libbpf: failed to load object 'minimal'
libbpf: failed to load BPF skeleton 'minimal': -22
ERR: minimal.c:20
Failed to open and load skel
not ok 1 minimal #
===== END =====
