ext4: rename ext4_has_free_blocks() to ext4_has_free_clusters()
Rename the function so it is more clear what is going on. Also rename the various variables so it's clearer what's happening. Also fix a missing blocks to cluster conversion when reading the number of reserved blocks for root. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
