[PATCH -next] fs: dlm: Fix build error without DEBUG_LOCK_ALLOC

[Zheng Yongjun]

If CONFIG_DLM is y, DEBUG_LOCK_ALLOC is n, building fails:

fs/dlm/lowcomms.o: In function `lowcomms_queue_rwork':
lowcomms.c:(.text+0x2ac): undefined reference to `lockdep_is_held'
lowcomms.c:(.text+0x308): undefined reference to `lockdep_is_held'
fs/dlm/lowcomms.o: In function `lowcomms_queue_swork':
lowcomms.c:(.text+0x3e0): undefined reference to `lockdep_is_held'
fs/dlm/lowcomms.o: In function `restore_callbacks':
lowcomms.c:(.text+0xd8c): undefined reference to `lockdep_is_held'
lowcomms.c:(.text+0xdcc): undefined reference to `lockdep_is_held'

Make DLM select DEBUG_LOCK_ALLOC to fix this.
