Agalakov Daniil d3baa34a47 e1000: check return value of e1000_read_eeprom ... [Why] e1000_set_eeprom() performs a read-modify-write operation when the write range is not word-aligned. This requires reading the first and last words of the range from the EEPROM to preserve the unmodified bytes. However, the code does not check the return value of e1000_read_eeprom(). If the read fails, the operation continues using uninitialized data from eeprom_buff. This results in corrupted data being written back to the EEPROM for the boundary words. Add the missing error checks and abort the operation if reading fails. Found by Linux Verification Center (linuxtesting.org) with SVACE.
