powerpc: Allow non-hcall return values for lparcfg writes
The code to handle writes to /proc/ppc64/lparcfg incorrectly assumes that the return code from the helper routines to update processor or memory entitlement return a hcall return value. It then assumes any non-hcall return value is bad and sets the return code for the write to be -EIO. The update_[mp]pp routines can return values other than a hcall return value. This patch removes the automatic setting of any return code that is not an hcall return value from these routines to -EIO.
