pfl->wcycle was set to 1 when the erase confirm command was set, which
lead to the next command being misinterpreted by Qemu:
pflash_write: Unimplemented flash cmd sequence (offset 00000000,
wcycle 0x1 cmd 0x20 value 0x70)
This patch fixes this issue by resetting pfl->wcycle to 0 on erase
confirm so that the next command is considered as a new one.
