IB/srp: Fix FMR mapping for 32-bit kernels and addresses above 4G
struct srp_device.fmr_page_mask was unsigned long, which means that
the top part of addresses above 4G was being chopped off on 32-bit
architectures. Of course nothing good happens when data from SRP
targets is DMAed to the wrong place.
Fix this by changing fmr_page_mask to u64, to match the addresses
actually used by IB devices.
Thanks to Brian Cain <Brian.Cain@ge.com> and David McMillen
<davem@systemfabricworks.com> for help diagnosing the bug and testing
the fix.
