When reading from pstore there is a buffer overflow during decompression due to the header added in unzip_oops. Remove unzip_oops and call pstore_decompress directly in nvram_pstore_read. Allocate buffer of size report_length of the oops header as header will not be deallocated in pstore. Since we have 'openssl' command line tool to decompress the compressed data, dump the compressed data in case decompression fails instead of not dumping anything.
