RFC - fix to at49xxxx crash during erase/program when interrupt happens


This fixes the crash when an interrupt happens during
flash erase/program for applications running out of flash.

Q: is eCos intended to support flash program/erase with interrupts
enabled for appliactions running out of flash?

Other:

- I should perhaps have added some #if's to 
disable this code when the appliaction is running out of RAM.
- Is it correct(i.e. a no-op) to invoke cyg_interrupt_disable/enable()
for
eCos configurations that do not have interrupts enabled?
