erofs-utils: lib: suppress a false-positive warning in kite-deflate
`gcc (Debian 13.2.0-2) 13.2.0` gives the following report:
kite_deflate.c: In function 'kite_deflate_writeblock':
kite_deflate.c:428:57: warning: 'distLevels' may be used uninitialized
[-Wmaybe-uninitialized]
428 | fixed ? 5 :
distLevels[distSlot]);
| ^
kite_deflate.c:393:34: note: 'distLevels' was declared here
393 | const u8 *litLenLevels, *distLevels;
Actually, `distLevels` won't be used in the static-huffman mode.
