[PATCH] staging: rtl8723bs: fix u8 less than zero check

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The error variable ret is currently a u8 and so two comparisons
to see if an error return is less than zero will always be false
because ret is unsigned.  Fix this by making ret an int.
