Subject: [PATCH 6.6 552/638] io_uring/net: correct the type of variable

From: Muhammad Usama Anjum <usama.anjum@...labora.com>

[ Upstream commit 86bcacc957fc2d0403aa0e652757eec59a5fd7ca ]

The namelen is of type int. It shouldn't be made size_t which is
unsigned. The signed number is needed for error checking before use.

Fixes: c55978024d12 ("io_uring/net: move receive multishot out of the generic msghdr path")
