[RFC PATCH 2/3] mtd: spi-nor: don't clear the SNOR_F_4B_OPCODES flag on failure

[Takahiro.Kuwano at infineon.com]

> 
> This was introduced in commit 548ed6847f530 ("mtd: spi-nor: Add the
> SNOR_F_4B_OPCODES flag"). It looks like it was the rollback mechanism if
> parsing the SFDP failed, but was setting that flag first. Nowadays, that
> flag can only be set if spi_nor_parse_4bait() was successful. IOW, the
> flags won't be left in an undefined state if parsing SFDP fails.
> 
> Remove the unneeded code to be able to rework spi_nor_init_params().
