ibmvnic: Fix endian error when requesting device capabilities
[ Upstream commit 28f4d16570dcf440e54a4d72666d5be452f27d0e ]
When a vNIC client driver requests a faulty device setting, the
server returns an acceptable value for the client to request.
This 64 bit value was incorrectly being swapped as a 32 bit value,
resulting in loss of data. This patch corrects that by using
the 64 bit swap function.
