    mtd: spinand: esmt: fix id code for F50D1G41LB
    
    Upon detecting the ID for the ESMT F50D1G41LB chip, the fifth byte
    returned is always 0x00 instead of the expected JEDEC continuation code
    of 0x7f. This causes detection to fail:
    
    [    0.304399] spi-nand spi0.0: unknown raw ID c8117f7f00
    [    0.508943] spi-nand: probe of spi0.0 failed with error -524
    
    So let's revert back to the 4 byte ID code for this chip
    specifically.
    
    Fixes: 4bd14b2fd8a8 ("mtd: spinand: esmt: Extend IDs to 5 bytes")
