Subject[PATCH] cdrom: remove unused variable
Date
The clang static analyzer reports the following warning,

File: drivers/cdrom/cdrom.c
Warning: line 1380, column 7
Although the value stored to 'status' is used in enclosing
expression, the value is never actually read from 'status'

Remove the unused variable to eliminate the warning.
