fs/resctrl: Modify struct rdt_parse_data to pass mode and CLOSID
parse_cbm() requires resource group mode and CLOSID to validate the capacity
bitmask (CBM). It is passed via struct rdtgroup in struct rdt_parse_data.
The io_alloc feature also uses CBMs to indicate which portions of cache are
allocated for I/O traffic. The CBMs are provided by user space and need to be
validated the same as CBMs provided for general (CPU) cache allocation.
parse_cbm() cannot be used as-is since io_alloc does not have rdtgroup context.
Pass the resource group mode and CLOSID directly to parse_cbm() via struct
rdt_parse_data, instead of through the rdtgroup struct, to facilitate calling
parse_cbm() to verify the CBM of the io_alloc feature.
