[PATCH -next v2] tls: rx: Fix unsigned comparison with less than zero

From: Yang Li
Date: Wed Jul 27 2022 - 23:10:41 EST


The return from the call to tls_rx_msg_size() is int, it can be
a negative error code, however this is being assigned to an
unsigned long variable 'sz', so making 'sz' an int.

Eliminate the following coccicheck warning:
./net/tls/tls_strp.c:211:6-8: WARNING: Unsigned expression compared with zero: sz < 0

Changes in v2:
--According to Jakub's suggestion
Keep the sorting of the variable lines from longest to shortest.
