memstick: Constify struct memstick_device_id
'struct memstick_device_id' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increases overall security.
Update memstick_dev_match(), memstick_bus_match() and struct
memstick_driver accordingly.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename

After:
=====
text data bss dec hex filename
74087 3423 88 77598 12f1e drivers/memstick/core/ms_block.o
