[PATCH -next] lightnvm: fix possible memory leak in nvme_nvm_get_l2p_tbl()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

'entries' is malloced in nvme_nvm_get_l2p_tbl() and should be freed
before leaving from the error handling cases, otherwise it will cause
memory leak.

Fixes: 8e79b5cb1d3b ("lightnvm: move block provisioning to targets")
