    fix: dev: set the in rsa exponent bounds to null after shutdown

    `dst__opensslrsa_shutdown` frees the resources consumed by the BIGNUMs
    used for checking RSA exponent bounds but does not set the pointers to
    `NULL`.

    This is not a real issue since there is no possible codepath that can
    deinitialize and initialize libdns. Nonetheless, set the freed resources
    to NULL for consistency with the rest of the codebase.

    Closes #6258

    Merge branch '6258-dst__opensslrsa_shutdown-frees-the-exponent-bignums-without-reset' into 'main'
