These patches are a pre-requisite to enable compilation for CXGBE PMD for
Windows OS. It currently uses Intel C++ compiler [1]. Our plan is to
integrate these compilation fixes to dpdk-next-net and then ask for a
pull request to pull these to dpdk-draft-windows tree [2].

These existing macros result in following errors in Windows build:

# cxgbe_compat.h(28): error : expected a ")"
    #define dev_printf(level, fmt, args...) \
                                       ^

# cxgbe_compat.h(31): error : expected a ")"
    #define dev_err(x, args...) dev_printf(ERR, args)

[...]
