[PATCH] mtd: spi-nor: cadence-quadspi: Fix the return value in case of error in 'cqspi_direct_read_execute()'

[Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>]

We return 0 unconditionally in 'cqspi_direct_read_execute()'.
However, 'ret' is set to some error codes in several error handling paths.

Return 'ret' instead to propagate the error code.
