[PATCH 1/2] ext4/045: skip test if the block size is 1k

["Theodore Ts'o" <tytso@mit.edu>]

If the file system is 1k, this test will fail because with dir_index
enabled, the directory tree will get too deep, and the kernel will
return ENOSPC and log the EXT4-fs warning "Directory (ino: NNN) index
full, reach max htree level: 2".  So if the blocksize is less than 2k,
_notrun this test.
