octeontx2-af: npc: cn20k: Drop debugfs_create_file() error checks in init

debugfs is not intended to be checked for allocation failures the way other
kernel APIs are: callers should not fail probe or subsystem init because a
debugfs node could not be created, including when debugfs is disabled in
Kconfig. Replacing NULL checks with IS_ERR() checks is similarly wrong for
optional debugfs.

Remove dentry checks and -EFAULT returns from npc_cn20k_debugfs_init().
