media: coda: fix memory corruption in case more than 32 instances are opened The ffz() return value is undefined if the instance mask does not contain any zeros. If it returned 32, the following set_bit would corrupt the debugfs_root pointer. Switch to IDA for context index allocation. This also removes the artificial 32 instance limit for all except CodaDx6.
