[PATCH] scsi: elx: efct: Avoid open coded arithmetic in memory allocation

[Christophe JAILLET]

kmalloc_array()/kcalloc() should be used to avoid potential overflow when
a multiplication is needed to compute the size of the requested memory.

So turn a kzalloc()+explicit size computation into an equivalent kcalloc().
