Eric Blake 1b4c0a0436 net: Drop unusual use of do { } while (0); ...

For a couple of macros in pcnet.c, we have to provide a new scope
to avoid compiler warnings about declarations in the middle of a
switch statement that aren't in a sub-scope.  But use of
'do { ... } while (0);' merely to provide that new scope is arcane
overkill, compared to just using '{ ... }'.
