ext4: Make ext4_meta_trans_blocks() non-static for later use 



Let's make ext4_meta_trans_blocks() non-static for use in later
functions during ->end_io conversion for atomic writes.
We will need this function to estimate journal credits for a special
case. Instead of adding another wrapper around it, let's make this
non-static.
