wifi: mwifiex: debugfs: Drop unnecessary error check for debugfs_create_dir()
[ Upstream commit 50180c7f8e3de7c2d87f619131776598fcb1478d ]
debugfs_create_dir() returns ERR_PTR and never return NULL.
As Russell suggested, this patch removes the error checking for
debugfs_create_dir(). This is because the DebugFS kernel API is developed
in a way that the caller can safely ignore the errors that occur during
the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in
start_creating() which can handle it gracefully. So these checks are
unnecessary.
