[PATCH v2] io_uring: fix typos and comment wording

[Alok Tiwari <alok.a.tiwari@oracle.com>]

Corrected spelling mistakes in comments
 "reuqests" -> "requests", "noifications" -> "notifications",
 "seperately" -> "separately").

Fixed a small grammar issue ("then" -> "than").
Updated "flag" -> "flags" in fdinfo.c
