ASoC: SOF: ipc4-mtrace: prevent underflow in sof_ipc4_priority_mask_dfs_write()

The "id" comes from the user.  Change the type to unsigned to prevent
an array underflow.

## Affected

- `linux_kernel >= 6.1, < 6.1.11`
- `linux_kernel = 6.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.1.11`
