net: Add parens to macro PSEUDO_HDR_SIZE

Smatch reports a warning about possibly needing parens around the macro
PSEUDO_HDR_SIZE. This will not affect the one place the macro is used
but add the parens anyway as it is good practice to have them and if the
macro is used again in the future it could possibly matter then.
