e2fsck: Fix a number of problems that were inappropriately using PROMPT_ABORT

There were a number of problems that were prompting the user whether
or not to ABORT, but then would abort regardless of whether the user
answered yes or no.  Change those to be PROMPT_NONE, PR_FATAL.

Also, fix PR_1_RESIZE_INODE_CREATE so that it recovers appropriately
after failing to create the resize inode.  This problem now uses
PROMPT_CONTINUE instead of PROMPT_ABORT, and if the user says, "no",
the code will abort.
