Joakim Tjernlund 7d0d52c003 mtd: cfi: cmdset_0002: Do not allow read/write to suspend erase block. 
commit 7b70eb1439 upstream.

Currently it is possible to read and/or write to suspend EB's.
Writing /dev/mtdX or /dev/mtdblockX from several processes may
break the flash state machine.

Taken from cfi_cmdset_0001 driver.
