staging: wilc1000: fix missing read_write setting when reading data
commit c58eef061dda7d843dcc0ad6fea7e597d4c377c0 upstream.
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")
