cpqarry: fix return value of cpqarray_init()
As reported by Dick Gevers on Compaq ProLiant:
Oct 13 18:06:51 dvgcpl kernel: Compaq SMART2 Driver (v 2.6.0)
Oct 13 18:06:51 dvgcpl kernel: sys_init_module: 'cpqarray'->init
suspiciously returned 1, it should follow 0/-E convention
Oct 13 18:06:51 dvgcpl kernel: sys_init_module: loading module anyway...
Oct 13 18:06:51 dvgcpl kernel: Pid: 315, comm: modprobe Not tainted
2.6.27-desktop-0.rc8.2mnb #1
Oct 13 18:06:51 dvgcpl kernel: [<c0380612>] ? printk+0x18/0x1e
Oct 13 18:06:51 dvgcpl kernel: [<c0158f85>] sys_init_module+0x155/0x1c0
Oct 13 18:06:51 dvgcpl kernel: [<c0103f06>] syscall_call+0x7/0xb
Oct 13 18:06:51 dvgcpl kernel: =======================
Make it return 0 on success and -ENODEV if no array was found.
