[PATCH] decompress_bunzip2: fix sizeof type in start_bunzip

[trix]

From: Tom Rix <t...@redhat.com>

clang static analysis flags this error

lib/decompress_bunzip2.c:671:13: warning: Result of 'malloc' is converted
  to a pointer of type 'unsigned int', which is incompatible with sizeof
  operand type 'int' [unix.MallocSizeof]
        bd->dbuf = large_malloc(bd->dbufSize * sizeof(int));
                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Reviewing the bunzip_data structure, the element dbuf is type

        /* Intermediate buffer and its size (in bytes) */
        unsigned int *dbuf, dbufSize;

So change the type in sizeof to 'unsigned int'

Fixes: bc22c17e12c1 ("bzip2/lzma: library support for gzip, bzip2 and lzma 
decompression")
