intel_th: gth: Fix an off-by-one in output unassigning
Commit9ed3f22223
("intel_th: Don't reference unassigned outputs") fixes a NULL dereference for all masters except the last one ("256+"), which keeps the stale pointer after the output driver had been unassigned. Fix the off-by-one. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com> Fixes:9ed3f22223
