eCryptfs: removed num_global_auth_toks from ecryptfs_mount_crypt_stat

Browse Source 
This patch removes the 'num_global_auth_toks' field of the
ecryptfs_mount_crypt_stat structure, used to count the number of items in
the 'global_auth_tok_list' list. This variable is not needed because there
are no checks based upon it.
