Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.

Replace all the fprintf(stderr, ...) calls with error_report.
Also make sure exit() consistently uses the error code 1. A few calls
used -1. While at it cleanup some indentation in the printf argument
lists.

The third argument to the fd_read() callback implemented by
ivshmem_read() is the number of bytes, not a flags field. Fix this and

If the user fails to specify 'chardev' or 'shm' then we cannot continue.
Exit right away so that we don't invoke shm_open(3) with a NULL pointer.
It would be nice to replace exit(1) with error returns in the PCI device
.init() function, but leave that for another patch since exit(1) is
currently used elsewhere.
