initialize buff to placate coverity (CIDs #1503942, #1504042)
Coverity doesn't realize that fr_sbuff_out_bstrncpy_allowed() will put something in buff, if only a NUL terminator. Until coverity sees annotations in macro definitions, the only way I know of to avoid the false positive "uninit_use_in_call" defects in SBUFF_PARSE_FLOAT_DEF()-generated functions is to actually initialize buff.
