error: Use error_report_err() instead of ad hoc prints
Unlike ad hoc prints, error_report_err() uses the error whole instead
of just its message obtained with error_get_pretty(). This avoids
suppressing its hint (see commit 50b7b00). Example:
$ bld/ivshmem-server -l 42@
Parameter 'shm_size' expects a size
You may use k, M, G or T suffixes for kilobytes, megabytes, gigabytes and terabytes.
The last line is new with this patch.
While there, drop a "cannot parse shm size: " message prefix; it's
redundant, because the error message proper is always of the form
"Parameter 'shm_size' expects ...".
