um/ptrace: Fix the syscall_trace_leave call

Browse source

Keep the same semantic as before the commit 26703c636c: deallocate
audit context and fake a proper syscall exit.

This fix a kernel panic triggered by the seccomp_bpf test:
> [ RUN      ] global.ERRNO_valid
> BUG: failure at kernel/auditsc.c:1504/__audit_syscall_entry()!
> Kernel panic - not syncing: BUG!

Fixes: 26703c636c ("um/ptrace: run seccomp after ptrace")
