sfdp.c : Initializing hbuf to avoid warnings generated by scan-build

scan-build uses the clang analyzer which is giving warnings
about garbage/undefined values in hbuf assigned to member of hdrs[0]
if hbuf is not initialized.

Though the path of the control flow shown by it in its html output
cannot occur in reality(since it assumes that (nph+1)*8 is <= 0 i.e
nph<=-1 but later assumes 0 <= nph ) hence its a false positive.
Still initializing all bytes of hbuf to 0 leads to the two warnings
for sfdp.c (one for hbuf, one for tbuf) to go away.
