    mtd: mtdcore: Fix build warning when CONFIG_MTD_CHAR is not defined
    
    Fix the following build warning:
    
    drivers/mtd/mtdcore.c: In function ‘mtd_release’:
    drivers/mtd/mtdcore.c:110: warning: unused variable ‘mtd’
    
    This happens when neither CONFIG_MTD_CHAR nor CONFIG_MTD_CHAR_MODULE are defined.
