[MTD] [CHIPS] cfi_cmdset_0001.c: Fix a bug in inval_cache_and_wait_for_operation().
If the inval_cache_and_wait_for_operation() is re-entered by write operation when erase
operation is in progress, the chip->erase_suspended will be cleared, this cause the erase
timeo is not reset and will result time out error for erase.
