Flash protection set on a device with MANW=1 was lost after reset. Since #2903 the driver honored MANW bit and issued Write Page command just for main flash write. This change adds similar technique to samd_modify_user_row(). Minor code improvements: samd_check_error() returns error code corresponding to error type instead of bool. samd_check_error() does not clear STATUS register if no error bit is set. Eliminated double error check in call sequence samd_issue_nvmctrl_command() folowed by samd_check_error(). Missing error code ERROR_FLASH_PROTECTED added to src/flash/common.h.
