flashrom.c: Drop redundant chip read validation in verify_range()

The 'chip_safety_check()' already validates the chip structure
within 'prepare_flash_access()' before all subsequent chip operations
such as 'verfy_range()' and therefore the chip structure is
guaranteed to be valid in the domain of those operations.
