mtd: onenand_base: Fix a memory leak bug

Browse source

In onenand_scan(), if CONFIG_MTD_ONENAND_VERIFY_WRITE is defined,
'this->verify_buf' is allocated through kzalloc(). However, it is not
deallocated in the following execution, if the allocation for
'this->oob_buf' fails, leading to a memory leak bug. To fix this issue,
free 'this->verify_buf' before returning the error.
