[PATCH][next] io_uring: Fix error returns when create_io_thread fails

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

The error return when create_io_thread calls fail is not using the
error return code from the returned pointer. Fix this by using
the error code in PTR_ERR(tsk).

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: c3c9a3194bd0 ("io_uring: move to using create_io_thread()")
