iscsi: Fix check for username
The variable user in struct iscsi_url is a character array, not a pointer.
Therefore its address will never be NULL.
clang reports this error:
block/iscsi.c:1329:20: warning:
comparison of array 'iscsi_url->user' not equal to a null pointer
is always true [-Wtautological-pointer-compare]
