spi: Fix error code checking in spi_mem_exec_op()
After commit cff49d58f57e ("spi: Unify error codes by replacing -ENOTSUPP with -EOPNOTSUPP"), our SPI NOR flashes would stop probing with the following visible in the kernel log: [ 2.196300] brcmstb_qspi f0440920.qspi: using bspi-mspi mode [ 2.210295] spi-nor: probe of spi1.0 failed with error -95 It turns out that the check in spi_mem_exec_op() was changed to check for -ENOTSUPP (old error code) or -EOPNOTSUPP (new error code), but this means that for drivers that were converted, the second condition is now true, and we stop falling through like we used to. Fix the error to check for neither error being neither -ENOTSUPP *nor* -EOPNOTSUPP.
