usb-storage: alauda: Check whether the media is initialized

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: usb-storage: alauda: Check whether the media is initialized The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba(). - Add a member "media_initialized" to struct alauda_info. - Change a condition in alauda_check_media() to ensure the first initialization. - Add an error check for the return value of alauda_init_media().
