lower-bitint: Fix a typo in a condition [PR113323]

The following testcase revealed a typo in condition, as the comment
says the intent is
       /*  If lhs of stmt is large/huge _BitInt SSA_NAME not in m_names
           it means it will be handled in a loop or straight line code
           at the location of its (ultimate) immediate use, so for
           vop checking purposes check these only at the ultimate
           immediate use.  */
but the condition was using != BITINT_TYPE rather than == BITINT_TYPE,
so e.g. it used bitint_precision_kind on non-BITINT_TYPEs (e.g. on vector
types it will crash because TYPE_PRECISION means something different there,
or on say INTEGER_TYPEs the precision will never be large enough to be >=
bitint_prec_large).

The following patch fixes that.
