[PATCH 2/8] common/cnxk: use for loop in shaper profiles cleanup

[Nithin Dabilpuram]

From: Gowrishankar Muthukrishnan <gmuthukri...@marvell.com>

In shaper profiles cleanup, KW reports infinite loop although existing
loop condition is alright. False positive may be due to tqh_first not
checked in loop, hence switching to FOREACH_SAFE to make KW happy.
