scsi: smartpqi: Map full length of PCI BAR 0

Browse Source 
Map full length of PCI BAR 0 at driver init.

During driver initialization, the driver must make a kernel call to map the
controller registers into kernel address space.  A parameter to this call
is the length of the memory to be mapped.  The driver was specifying the
wrong length.
