octeontx2-pf: Fix leak of SQ timestamp buffer on teardown

The send-queue timestamp ring is allocated with qmem_alloc() when
timestamping is used, but otx2_free_sq_res() never freed sq->timestamps,
leaking that memory across ifdown and device removal.  Add the missing
qmem_free() alongside the other SQ companion buffers.
