[PATCH] staging: wilc1000: fix missing read_write setting when reading data

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

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")

Fixes: c5c77ba18ea6 ("staging: wilc1000: Add SDIO/SPI 802.11 driver")
