Vikas Shivappa 4797b7dfdf x86/intel_rdt: Return error for incorrect resource names in schemata
When schemata parses the resource names it does not return an error if it
detects incorrect resource names and fails quietly.

This happens because for_each_enabled_rdt_resource(r) leaves "r" pointing
beyond the end of the rdt_resources_all[] array, and the check for !r->name
results in an out of bounds access.

Split the resource parsing part into a helper function to avoid the issue.

[ tglx: Made it readable by splitting the parser loop out into a function ]
