[PATCH -next] lightnvm: pblk: fix error handling of pblk_lines_init()

[Wei Yongjun]

In the too many bad blocks error handling case, we should release all
the alloced resources instead direct return, otherwise it will cause
memory leak.

Fixes: 2deeefc02dff ("lightnvm: pblk: fail gracefully on line alloc. failure")
