mtd: spi-nor: fix flash probing
Fix flash probing by name. Flash entries without a name are allowed since commit15eb8303bb
("mtd: spi-nor: mark the flash name as obsolete"). But it was just until recently that a flash entry without a name was actually introduced. This triggers a bug in the legacy probe by name path. Skip entries without a name to fix it. Fixes:2095e7da80
