From: Ruiqiang Hao <ruiqiang....@windriver.com>
commit bbf258fecfff ("Merge branch 'v6.1/standard/base' into v6.1/
standard/cn-sdkv5.15/octeon") introduced redundant mbox sync operation,
which will cause error when processing message NIX_TXSCH_ALLOC. Remove
this invoking to solve the error below.
rvu_af 0002:01:00.0: Error -406 when processing message NIX_TXSCH_ALLOC
(0x8004) from PF2
rvu_nicpf 0002:03:00.0: Mbox msg response has err -406, ID 0x8004
rvu_nicpf 0002:03:00.0: Failed to allocate TXSCH
