[PATCH sched_ext/for-7.1] sched_ext: Make string params of __ENUM_set() const

[Kuba Piecuch]

A small change to improve type safety/const correctness.
__COMPAT_read_enum() already has const string parameters.

It fixes a warning when using the header in C++ code:

  error: ISO C++11 does not allow conversion from string literal
         to 'char *' [-Werror,-Wwritable-strings]

That's because string literals have type char[N] in C and
const char[N] in C++.

Not sure whether upstream cares about C++, but figured I'd send it in
anyway. Also not sure if it merits CC'ing stable (probably not?)
Would appreciate your input!
