lightnvm: pblk: fix resource leak of invalid_bitmap
Currently the error exit path when the emeta could not be
interpreted is via fail_free_ws and this fails to free
invalid_bitmap. Fix this by adding another exit label and
exiting via this to kfree invalid_bitmap.
Detected by CoverityScan, CID#1469659 ("Resource leak")
Fixes: 48b8d20895f8 ("lightnvm: pblk: garbage collect lines with failed writes")
