[clang-tidy] fix crash due to assumed callee in min-max-use-initializer-list (#91992)

Previously, the call to `findArgs` for a `CallExpr` inside of a `min` or
`max` call would call `findArgs` before checking if the argument is a
call to `min` or `max`, which is what `findArgs` is expecting.
The fix moves the name checking before the call to `findArgs`, such that
only a `min` or `max` function call is used as an argument.
