[PATCH] target: Call proc_mkdir + remove_proc_entry with NULL parameter

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

This patch makes proc_mkdir() and remove_proc_entry() use a NULL
parameter to fix the following sparse warning:

CHECK   drivers/target/target_core_configfs.c
drivers/target/target_core_configfs.c:3131:54: warning: Using plain integer as NULL pointer
drivers/target/target_core_configfs.c:3145:50: warning: Using plain integer as NULL pointer
drivers/target/target_core_configfs.c:3212:42: warning: Using plain integer as NULL pointer
