In mtdoops driver, to comply with latest kernel code requirement, change
printk() to counterpart pr_ functions. [Note: change to pr_debug() may
cause behavior difference.] Add mtdoops_erase function; When panic
function invokes mtdoops, if needed, call mtdoops_erase function
immediately.

To comply with latest kernel code requirement, change printk() to
counterpart pr_ functions in mtdoops driver:
- change printk(INFO) to pr_info()
- change printk(DEBUG) to pr_debug()
- change printk(WARNING) to pr_warn()
- change printk(ERR) to pr_err()
Note that only if dynamic debugging is enabled or DEBUG is defined,
printk(KERN_DEBUG) and pr_debug() are equivalent; Otherwise pr_debug()
is no-op, causing different behavior.

Preparing for next patch with minimal code difference, add mtdoops_erase
function and move mtdoops_inc_counter to after it, with no functional
change.

The panic function disables the local interrupts, preemption, and all
other processors. When the invoked mtdoops needs to erase a used page,
calling schedule_work() to do it will not work. Instead, just call
mtdoops_erase function immediately.
Tested:
