[U-Boot] [PATCH] sparc: fix return value of disable_interrupts

[DUHAMEL Benoit]

The return value of disable_interrupts for SPARC is incorrect (false when all interrupts were enabled).
As it may be used to allow re-enabling, this may causes hangs up.
Observed issue on FLASH write (flash_write_cfiword  in drivers/mtd/cfi_flash.c)
