[PATCH] scsi: pm8001: Fix the warning when failing at the probe time

[Zheyu Ma]

When the driver fails at chip_init(), we will get the following warning:

[    7.778705] remove_proc_entry: removing non-empty directory 'irq/21', leaking at least 'pm80xx0'
[    7.779414] WARNING: CPU: 0 PID: 290 at fs/proc/generic.c:720 remove_proc_entry+0x389/0x3f0
[    7.782793] RIP: 0010:remove_proc_entry+0x389/0x3f0
[    7.790813] Call Trace:
[    7.791284]  unregister_irq_proc+0x14c/0x170
[    7.793043]  pci_disable_device+0x1ad/0x380
[    7.793396]  pm8001_pci_probe+0x6d9/0xd40 [pm80xx]

Fix this by free the irq before disabling the pci device.
