Handle leak in bit-rot-stub

[sminux]

Description of problem:
The handle 'fd_ctx->bad_object->dir' is created at syscall.c:149 by calling function 'sys_opendir' at bit-rot-stub.c:2690

glusterfs/xlators/features/bit-rot/src/stub/bit-rot-stub.c

Line 2690 in 929d71b

fd_ctx->bad_object.dir = sys_opendir(priv->stub_basepath);

and lost at bit-rot-stub.c:2698.

Do we need to add sys_closedir(fd_ctx->bad_object.dir);
