scsi: device_handler: remove VLAs
In preparation to enabling -Wvla, remove VLAs and replace them with
fixed-length arrays instead.
scsi_dh_{alua,emc,rdac} use variable-length array declarations to store
command blocks, with the appropriate size as determined by
COMMAND_SIZE. This patch replaces these with fixed-sized arrays using
MAX_COMMAND_SIZE, so that the array size can be determined at compile
time.
This was prompted by https://lkml.org/lkml/2018/3/7/621
