If the work item is already queued,\nthe incremented refcount is never decremented.\n\nFix this by checking the return value of queue_work() and decrementing\nthe refcount when necessary.\n\nResolves:\n\nUnreferenced object 0xffff9d9f421e3d80 (size 192):\n  comm \"cryptomgr_probe\", pid 157, jiffies 4294694003\n  hex dump (first 32 bytes):\n    80 8b cf 41 9f 9d ff ff b8 97 e0 89 ff ff ff ff  ...A............\n    d0 97 e0 89 ff ff ff ff 19 00 00 00 1f 88 23 00  ..............#.\n  backtrace (crc 838fb36):\n    __kmalloc_cache_noprof+0x284/0x320\n    padata_alloc_pd+0x20/0x1e0\n    padata_alloc_shell+0x3b/0xa0\n    0xffffffffc040a54d\n    cryptomgr_probe+0x43/0xc0\n    kthread+0xf6/0x1f0\n    ret_from_fork+0x2f/0x50\n    ret_from_fork_asm+0x1a/0x30",
