powercap / RAPL: fix BIOS lock check
Intel RAPL initialized on several systems where the BIOS lock bit (msr
0x610, bit 63) was set. This occured because the return value of
rapl_read_data_raw() was being checked, rather than the value of the variable
passed in, locked.
This patch properly implments the rapl_read_data_raw() call to check the
variable locked, and now the Intel RAPL driver outputs the warning:
intel_rapl: RAPL package 0 domain package locked by BIOS
and does not initialize for the package.
