rtl8139: fix regression in TxStatus/TxAddr read
Commit afe0a595356192 added byte reads for TxStatus/TxAddr, but
broke 32-bit reads; the mask generation
(1 << (8 * size)) - 1
is unspecified in C for size >= sizeof(int), and in fact returns 0
on x86.
Fix by using a larger type.
Fixes (at least) Fedora 9 i386 with -machine kernel_irqchip=on. I
didn't see it with the qemu APIC implementation; may be due to timing
or (more likely) a tester error.
