orangefs: Fix sysfs not cleanup when dev init failed
When the dev init failed, should cleanup the sysfs, otherwise, the module will never be loaded since can not create duplicate sysfs directory: sysfs: cannot create duplicate filename '/fs/orangefs' CPU: 1 PID: 6549 Comm: insmod Tainted: G W 6.0.0+ #44 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x34/0x44 sysfs_warn_dup.cold+0x17/0x24 sysfs_create_dir_ns+0x16d/0x180 kobject_add_internal+0x156/0x3a0 kobject_init_and_add+0xcf/0x120 orangefs_sysfs_init+0x7e/0x3a0 [orangefs] orangefs_init+0xfe/0x1000 [orangefs] do_one_initcall+0x87/0x2a0 do_init_module+0xdf/0x320 load_module+0x2f98/0x3330 __do_sys_finit_module+0x113/0x1b0 do_syscall_64+0x35/0x80 entry_SYSCALL_64_after_hwframe+0x46/0xb0 kobject_add_internal failed for orangefs with -EEXIST, don't try to register things with the same name in the same directory.
