[PATCH v4 5/5] nvme: remove nvme_dev_uring_cmd() IO_URING_F_IOPOLL check

[Caleb Sander Mateos]

nvme_dev_uring_cmd() is part of struct file_operations nvme_dev_fops,
which doesn't implement ->uring_cmd_iopoll(). So it won't be called with
issue_flags that include IO_URING_F_IOPOLL. Drop the unnecessary
IO_URING_F_IOPOLL check in nvme_dev_uring_cmd().
