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: 302d3deb20 ("xprtrdma: Prevent inline overflow")
