octeontx2-af: fix the double free in rvu_npc_freemem()

Browse Source 
Clang static checker(scan-build) warning：
drivers/net/ethernet/marvell/octeontx2/af/rvu_npc.c:line 2184, column 2
Attempt to free released memory.

npc_mcam_rsrcs_deinit() has released 'mcam->counters.bmap'. Deleted this
redundant kfree() to fix this double free problem.
