Liu Jian 2303321f9a mtd: cfi: fix deadloop in cfi_cmdset_0002.c do_write_buffer 
commit d9b8a67b3b upstream.

In function do_write_buffer(), in the for loop, there is a case
chip_ready() returns 1 while chip_good() returns 0, so it never
break the loop.
To fix this, chip_good() is enough and it should timeout if it stay
bad for a while.
