[PATCH v2] sched/rt: Fix unused-const-variable W=1 warning and style issue

[Anuradha Weeraman]

Compiler warning with W=1 due to unused constant in
    kernel/sched/rt.c:9:18: warning: ‘max_rt_runtime’ defined but not used

Fix by adding __maybe_unused attribute to max_rt_runtime.

Also, fix style issue for "else should follow close brace '}'".
