xfs: prevent kernel crash due to corrupted inode log format
Andras Korn reported an oops on log replay causes by a corrupted
xfs_inode_log_format_t passing a 0 size to kmem_zalloc. This patch handles
to small or too large numbers of log regions gracefully by rejecting the
log replay with a useful error message.
