Subject: [PATCH 5.4 009/183] net/iucv: fix the allocation size of iucv_path_table array

From: Alexander Gordeev <agordeev@...ux.ibm.com>

[ Upstream commit b4ea9b6a18ebf7f9f3a7a60f82e925186978cfcf ]

iucv_path_table is a dynamically allocated array of pointers to
struct iucv_path items. Yet, its size is calculated as if it was
an array of struct iucv_path items.
