    ath25: fix compilation for AR2315 MTD driver
    
    Kernel commit e7bfb3fdbde3 ("mtd: Stop updating erase_info->state
    and calling mtd_erase_callback()") removed erase_info->state
    updates and calls of mtd_erase_callback().
    
    Drop these erase callback invocations from AR2315 MTD driver as well.
