scsi: ufs_quirks: fix card model string copy

Browse source 
Product name string (referred as "model" string in driver) starts from
offset 02h in Product Name String Descriptor but currently we copy the
product name from 00h offset of the descriptor which is incorrect.
This change fixes the above problem by copying the product name from
the right offset of the Product Name String Descriptor.
