powerpc/pseries/setup: 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.
pSeries_cmo_feature_init() ignores this, making it possible to fail to
detect cooperative memory overcommit capabilities during boot.
Move the RTAS call into a conventional rtas_busy_delay()-based
loop, dropping unnecessary clearing of rtas_data_buf.
