[PATCH 23/46] common/sfc_efx/base: allow for const in MCDI struct accessor

[Ivan Malov]

The existing code is fine, however, future patches will need
to use this macro on buffers that are passed by callers with
const qualifier. With 'cast-qual' enabled, this macro causes
compile warnings in such cases. Rework it to allow for const.
