Colin Ian King c58eef061d staging: wilc1000: fix missing read_write setting when reading data
Currently the cmd.read_write setting is not initialized so it contains
garbage from the stack.  Fix this by setting it to 0 to indicate a
read is required.

Detected by CoverityScan, CID#1357925 ("Uninitialized scalar variable")
