wifi: cfg80211: debugfs: fix return type in ht40allow_map_read()
[ Upstream commit d776763f48084926b5d9e25507a3ddb7c9243d5e ]
The return type is supposed to be ssize_t, which is signed long,
but "r" was declared as unsigned int. This means that on 64 bit systems
we return positive values instead of negative error codes.
