scsi: ufs: core: scsi_get_lba() error fix
commit 2bd3b6b75946db2ace06e145d53988e10ed7e99a upstream.
When ufs initializes without scmd->device->sector_size set, scsi_get_lba()
will get a wrong shift number and trigger an ubsan error. The shift
exponent 4294967286 is too large for the 64-bit type 'sector_t' (aka
'unsigned long long').
Call scsi_get_lba() only when opcode is READ_10/WRITE_10/UNMAP.
