Subject: coda: get rid of CODA_ALLOC()

These days we have kvzalloc() so we can delete CODA_ALLOC().

I made a couple related changes in coda_psdev_write().  First, I added
some error handling to avoid a NULL dereference if the allocation failed. 
Second, I used kvmalloc() instead of kvzalloc() because we copy over the
memory on the next line so there is no need to zero it first.
