In libzutil, for zpool_search_import and zpool_find_config, we use
libpc_handle_t internally, which does not maintain error code and it is
not exposed in the interface. Due to this, the error information is not
propagated to the caller. Instead, an error message is printed on
stderr.
This commit adds lpc_error field in libpc_handle_t and exposes it in
the interface, which can be used by the users of libzutil to get the
appropriate error information and handle it accordingly.
Users of the API can also control if they want to print the error
message on stderr.

Coverity caught these. With the exception of the file descriptor leak in
tests/zfs-tests/cmd/draid.c, they are all memory leaks.
Also, there is a piece of dead code in zfs_get_enclosure_sysfs_path().
We delete it as cleanup.
