io/nand: Some trivial cleanups, partly to work with gcc 4.7, and partly as I noticed them. Details:
* src/nand_bbt.c (LOCK_PAGEBUF, UNLOCK_PAGEBUF, bbti_incorporate_one,
bbti_write_one_table): Remove all uses of i_locked variable as it
wasn't really used.
* tests/nand_eccequiv.c (cyg_user_start): Don't use CYG_ASSERTC checks,
which only tests for debug builds. Use MUST instead.
* tests/nand_readwrite.c (cyg_user_start): Ditto.
* tests/nand_sweccwalk.c (cyg_user_start): Ditto.
