[PATCH i-g-t v2 6/8] tests/intel/kms_fbcon_fbt: use a bigger fbc status buffer

[Vinod Govindapillai <vinod.govindapillai@intel.com>]

As the FBC status now include plane specific FBC status as well, we
need a bigger buffer to capture the complete FBC status. Use the
already defined buffer length to assess the FBC status
