rdma: Fix representation of PortInfo CapabilityMask

The port capability mask represents IBTA PortInfo specification,
but as it is written in description of kernel commit 2f944c0fbf58
("RDMA: Fix storage of PortInfo CapabilityMask in the kernel"),
the bit 26 was mistakenly overwritten.

The rdmatool followed it too and mislead users by presenting wrong
value. Since it never showed proper value, we update the whole
port_cap_mask to comply with IBTA and show real HW values.
