Subject: [PATCH] e2fsck: fix type mismatches in quota warning message

The conversion operations in the format control strings found in the
fprintf call used to print the quota warning message do not match the
types of their corresponding arguments.  Although this probably hasn't
generally been a problem, it obfuscates a bigalloc quota accounting bug
where the reported actual quota goes negative.

Clean up the mismatches and some unnecessary casts.  While we're at it,
fix a spelling nit in a related comment.
