cxgb: avoid open-coded offsetof()
clang-14 does not like the custom offsetof() macro in vsc7326:
drivers/net/ethernet/chelsio/cxgb/vsc7326.c:597:3: error: performing pointer subtraction with a null pointer has undefined behavior [-Werror,-Wnull-pointer-subtraction]
HW_STAT(RxUnicast, RxUnicastFramesOK),
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/chelsio/cxgb/vsc7326.c:594:56: note: expanded from macro 'HW_STAT'
{ reg, (&((struct cmac_statistics *)NULL)->stat_name) - (u64 *)NULL }
Rewrite this to use the version provided by the kernel.
