Bob Copeland 9419fc1c95 omfs: fix oops when file metadata is corrupted
A fuzzed fileystem image failed with OMFS when the extent count was
used in a loop without being checked against the max number of extents.
It also provoked a signed division for an array index that was checked
as if unsigned, leading to index by -1.

omfsck will be updated to fix these cases, in the meantime bail out
gracefully.
