isobusfs: fix printf format specifiers in log messages

Several log messages used format specifiers which did not match the
types of the provided arguments (e.g. %d or %i for size_t/ssize_t,
%ld for int64_t/time_t and size_t for the '.*' precision). On 64 bit
hosts (and for int64_t/time_t on 32 bit hosts) this leads to wrong
output or undefined behaviour when the log level is enabled.

Additionally the seek response position was compared to the requested
offset without le32toh() conversion which fails on big endian hosts.

Fix the format specifiers and add the missing le32toh() conversion.
