powerpc/pseries/lparcfg: add missing RTAS retry status handling
The ibm,get-system-parameter RTAS function may return -2 or 990x,
which indicate that the caller should try again.
lparcfg's parse_system_parameter_string() ignores this, making it
possible to intermittently report incorrect SPLPAR characteristics.
Move the RTAS call into a coventional rtas_busy_delay()-based loop.
