rtas_st_buffer() appears in spapr.h as though it were a widely used helper,
but in fact it is only used for saving data in a format used by
rtas_ibm_get_system_parameter(). This changes it to a local helper more
specifically for that function.
While we're there fix a couple of small defects in
rtas_ibm_get_system_parameter:
- For the string value SPLPAR_CHARACTERISTICS, it wasn't including the
terminating \0 in the length which it should according to LoPAPR
7.3.16.1
- It now checks that the supplied buffer has at least enough space for
the length of the returned data, and returns an error if it does not.
