[PATCH v2 16/19] common/cnxk: fix null SQ access

[Nithin Dabilpuram <ndabilpuram@marvell.com>]

From: Satha Rao <skoteshwar@marvell.com>

Condition to check SQ is non NULL before access. Also pktio locks
are simplified while doing threshold_profile config.

Fixes: 90a903ffa6eb ("common/cnxk: split NIX TM hierarchy enable API")
