[PATCH] io_uring/napi: Remove unnecessary s64 cast

From: Thorsten Blum
Date: Tue Jul 09 2024 - 21:06:11 EST


Since the do_div() macro casts the divisor to u32 anyway, remove the
unnecessary s64 cast and fix the following Coccinelle/coccicheck
warning reported by do_div.cocci:

WARNING: do_div() does a 64-by-32 division, please consider using div64_s64 instead
