Thomas Weißschuh 3f7fbde4cd vdso/datastore: Mark vdso_k_*_data pointers as __ro_after_init 
These pointers are only modified once in vdso_setup_data_pages(),
during the init phase. Make them read-only after that.

Drop __refdata as that would conflict with __ro_after_init.
Modpost does accept the reference from a __ro_after_init symbol to
an __init one.
