UBI: print a warning if too many PEBs are corrupted
There was a bug report recently where UBI prints:
UBI error: ubi_attach_mtd_dev: failed to attach by scanning, error -22
error messages and refuses to attach a PEB. It turned out to be a
buggy flash driver which returned garbage to almost every UBI read.
This patch makes UBI print a better message in such cases. Namely,
if UBI finds 8 or more corrupted PEBs, it prints a warning and
lists the corrupted PEBs.
