[PATCH] Revert "mtd: spi-nor: core: Return error code from set_4byte_addr_mode()"

[Mika Westerberg]

This reverts commit 08412e72afba3a2daef3e7f3378c3753255a0017.

The Intel SPI-NOR controller does not support this opcode so the driver
ends up returning -EOPNOTSUPP and that makes the SPI flash chip probe
fail like this:

  [ 12.291082] spi-nor: probe of spi0.0 failed with error -524

Whereas previously it worked just fine (and hence the return value
probably was ignored in the first place).
