From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
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")
