soreuseport: fix use of uid in tb->fastuid 

Fix a reported compilation error where ia variable of type kuid_t
was being set to zero.

Eliminate two instances of setting tb->fastuid to zero.  tb->fastuid is
only used if tb->fastreuseport is set, so there should be no problem if
tb->fastuid is not initialized (when tb->fastreuesport is zero).
