scsi: qla2xxx: Fix sparse warnings triggered by the PCI state checking code

Browse Source 
This patch fixes the following sparse warnings:

drivers/scsi/qla2xxx/qla_mbx.c:120:21: warning: restricted pci_channel_state_t degrades to integer
drivers/scsi/qla2xxx/qla_mbx.c:120:37: warning: restricted pci_channel_state_t degrades to integer

>From include/linux/pci.h:

enum pci_channel_state {
	/* I/O channel is in normal state */
	pci_channel_io_normal = (__force pci_channel_state_t) 1,

	/* I/O to channel is blocked */
	pci_channel_io_frozen = (__force pci_channel_state_t) 2,

	/* PCI card is dead */
	pci_channel_io_perm_failure = (__force pci_channel_state_t) 3,
};
