[PATCH 22.11] common/cnxk: fix CPT backpressure disable on LBK

[Rahul Bhansali <rbhansali@marvell.com>]

[ upstream commit 772e30281a1d686096b27e5926e2f369caa05cff ]

For LBK interfaces, roc_nix_inl_inb_is_enabled() is false, hence
backpressure on CPT is disabled and causing CQ full interrupt.

NIXX_AF_RX_CHAN[0x800]_CFG is global config for all PF, VF
of RPM/LBK, hence backpressure disable on CPT is not required.

Fixes: 0663a84524e5 ("common/cnxk: enable backpressure on CPT with inline inbound")
