ext4: skip ext4_init_security() and encryption on ea_inodes

Browse Source 
Extended attribute inodes are internal to ext4. Adding encryption/security
related attributes on them would mean dealing with nested calls into ea code.
Since they have no direct exposure to user mode, just avoid creating ea
entries for them.
