mtd: *nftl: return -ENOMEM when kmalloc failed 

The driver is using -1 instead of the -ENOMEM defined macro to
specify that a buffer allocation failed. Using the correct error
code is more intuitive

Smatch tool warning:
drivers/mtd/inftlmount.c:333 check_free_sectors() warn: returning -1
instead of -ENOMEM is sloppy
drivers/mtd/nftlmount.c:272 check_free_sectors() warn: returning -1
instead of -ENOMEM is sloppy

No functional change, just more standardized.
