nbd: Fix debugfs_create_dir error checking
[ Upstream commit 4913cfcf014c95f0437db2df1734472fd3e15098 ]
The debugfs_create_dir function returns ERR_PTR in case of error, and the
only correct way to check if an error occurred is 'IS_ERR' inline function.
This patch will replace the null-comparison with IS_ERR.
