lightnvm: fix uninitialized pointer in nvm_remove_tgt()
With gcc 4.1: drivers/lightnvm/core.c: In function ‘nvm_remove_tgt’: drivers/lightnvm/core.c:510: warning: ‘t’ is used uninitialized in this function Indeed, if no NVM devices have been registered, t will be an uninitialized pointer, and may be dereferenced later. A call to nvm_remove_tgt() can be triggered from userspace by issuing the NVM_DEV_REMOVE ioctl on the lightnvm control device. Fix this by preinitializing t to NULL.
