[PATCH 19/30] usb: storage: alauda: Remove set but unchecked variable

[Lee Jones]

The return value of alauda_get_media_status() hasn't been checked
since the driver's inception back in 2005.  If nothing have gone
wrong/been detected until this point, it's probably safe to just
remove the variable.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/storage/alauda.c: In function âalauda_check_mediaâ:
 drivers/usb/storage/alauda.c:456:6: warning: variable ârcâ set but not used [-Wunused-but-set-variable]
 456 | int rc;
 | ^~
