[PATCH net-next v3] af_unix: Fix undefined 'other' error

[Purva Yeshi]

Fix an issue detected by the Smatch static analysis tool where an
"undefined 'other'" error occurs due to `__releases(&unix_sk(other)->lock)`
being placed before 'other' is in scope.

Remove the `__releases()` annotation from the `unix_wait_for_peer()`
function to eliminate the Smatch warning. The annotation references `other`
before it is declared, leading to a false positive error during static
analysis.

Since AF_UNIX does not use Sparse annotations, this annotation is
unnecessary and does not impact functionality.
