f2fs: reserve the xattr space dynamically
This patch enables the number of direct pointers inside on-disk inode block to be changed dynamically according to the size of inline xattr space. The number of direct pointers, ADDRS_PER_INODE, can be changed only if the file has inline xattr flag. The number of direct pointers that will be used by inline xattrs is defined as F2FS_INLINE_XATTR_ADDRS. Current patch assigns F2FS_INLINE_XATTR_ADDRS to 0 temporarily.
