[PATCH v2 6/7] rust: irq: always inline functions using build_assert with arguments

[Alexandre Courbot <acourbot@nvidia.com>]

`build_assert` relies on the compiler to optimize out its error path.
Functions using it with its arguments must thus always be inlined,
otherwise the error path of `build_assert` might not be optimized out,
triggering a build error.
