erasure_layout: Fix init_eraseblock segmentation fault

Fix a segmentation fault that is caused by accessing an invalid
"subedata" pointer on the last iteration of the init_eraseblock loop.
Instead, short circuit the loop condition to check the sub block index
first, and do not access the invalid pointer if it is the last sub
block.
