usb: storage: alauda: Remove set but unchecked variable
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 ‘alauda_check_media’:
drivers/usb/storage/alauda.c:456:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable]
456 | int rc;
