libdecnumber: Eliminate Unused Variable in decSetSubnormal
Eliminate an unused variable in the decSetSubnormal routine. The variable dnexp is declared and eventually set but never used, and thus may trigger an unused-but-set-variable warning. Signed-off-by: Tom Musta <tommusta@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
