Subject: [PATCH] staging: wilc1000: fix missing read_write setting when reading data
Git-commit: c58eef061dda7d843dcc0ad6fea7e597d4c377c0
Patch-mainline: v5.0-rc1
References: bsc#1051510

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.
