Subject: [PATCH] rtw88: remove redundant assignment to pointer debugfs_topdir

From: Colin Ian King <colin.king@...onical.com>

Pointer debugfs_topdir is initialized to a value that is never read
and it is re-assigned later. The initialization is redundant and can
be removed.

Addresses-Coverity: ("Unused value")
