security: Fix ret values doc for security_inode_init_security()
Commit 6bcdfd2cac55 ("security: Allow all LSMs to provide xattrs for inode_init_security hook") unified the !initxattrs and initxattrs cases. By doing that, security_inode_init_security() cannot return -EOPNOTSUPP anymore, as it is always replaced with zero at the end of the function. Also, mentioning -ENOMEM as the only possible error is not correct. For example, evm_inode_init_security() could return -ENOKEY. Fix these issues in the documentation of security_inode_init_security().
