Subject: net: mscc: ocelot: avoid incorrect consuming in skbs list
Git-commit: fc62c0948986b7aa6b2871a450a4469e35c5f9bc
Patch-mainline: v5.5-rc1
References: jsc#SLE-9263
Break the matching loop when find the matching skb for TX timestamp.
This is to avoid consuming more skbs incorrectly. The timestamp ID
is from 0 to 3 while the FIFO could support 128 timestamps at most.
