octeontx2-pf: Fix potential memory leak in otx2_init_tc()
[ Upstream commit fbf33f5ac76f2cdb47ad9763f620026d5cfa57ce ]
In otx2_init_tc(), if rhashtable_init() failed, it does not free
tc->tc_entries_bitmap which is allocated in otx2_tc_alloc_ent_bitmap().
Fixes: 2e2a8126ffac ("octeontx2-pf: Unify flow management variables")
