[PATCH V2 30/31] staging: ks7010: drop counting sd errors

[Wolfram Sang <wsa@xxxxxxxxxxxxx>]

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

They were counted but never really used anywhere. Also change the printk
to a debug print, since it mostly shows on the expected -ENOMEDIUM on
card removal.
