xprtrdma: fix incorrect header size calculations
Currently the header size calculations are using an assignment operator instead of a += operator when accumulating the header size leading to incorrect sizes. Fix this by using the correct operator. Addresses-Coverity: ("Unused value") Fixes: 302d3deb2068 ("xprtrdma: Prevent inline overflow") Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
