nilfs2: put out gfp mask manipulation from nilfs_set_inode_flags()
nilfs_set_inode_flags() function adjusts gfp-mask of inode->i_mapping as well as i_flags, however, this coupling of operations is not appropriate. For instance, nilfs_ioctl_setflags(), one of three callers of nilfs_set_inode_flags(), doesn't need to reinitialize the gfp-mask at all. In addition, nilfs_new_inode(), another caller of nilfs_set_inode_flags(), doesn't either because it has already initialized the gfp-mask. Only __nilfs_read_inode(), the remaining caller, needs it. So, this moves the gfp mask manipulation to __nilfs_read_inode() from nilfs_set_inode_flags().
