iscsi: iscsi_target: fix clang -Wformat warning

When building with Clang we encounter this warning:

| drivers/target/iscsi/iscsi_target.c:4365:12: error: format specifies
| type 'unsigned short' but the argument has type 'int' [-Werror,-Wformat]
| " %s\n", atomic_read(&sess->nconn)

The format specifier used is %hu which describes an unsigned short. However, atomic_read returns an int which means the format specifier should be %d.
