NTB: ntb_transport: Fix too small buffer for debugfs_name

Browse Source 
[ Upstream commit 6a4b50585d ]

The buffer used for "qp%d" was only 4 bytes, which truncates names like
"qp10" to "qp1" and causes multiple queues to share the same directory.

Enlarge the buffer and use sizeof() to avoid truncation.
