[PATCH] io_uring: remove redundant assignment to ret in io_register_iowq_max_workers()

[Nghia Le <nghialm78@gmail.com>]

After the assignment, only exit path with label 'err' uses ret as
return value. However,before exiting through this path with label 'err',
ret is assigned with the return value of io_wq_max_workers(). Hence, the
initial assignment is redundant and can be removed.
