iscsi-target: Fix potential NULL pointer in solicited NOPOUT reject

This patch addresses a potential NULL pointer dereference regression in
iscsit_setup_nop_out() code, specifically for two cases when a solicited
NOPOUT triggers a ISCSI_REASON_PROTOCOL_ERROR reject to be generated.

This is because iscsi_cmd is expected to be NULL for solicited NOPOUT
case before iscsit_process_nop_out() locates the descriptor via TTT
using iscsit_find_cmd_from_ttt().

This regression was originally introduced in:
