[Nbd] [PATCH 2/2] gznbd: fix warning with newer zlib

[Mike Frysinger <vapier@...103...>]

When you build against newer zlib, you get a lot of warnings like so:

gznbd.c: In function 'main':
gznbd.c:87:5: warning: assignment from incompatible pointer type [enabled by default]
gznbd.c:109:5: warning: passing argument 1 of 'gzread' from incompatible pointer type [enabled by default]
In file included from gznbd.c:37:0:
/usr/include/zlib.h:1313:21: note: expected 'gzFile' but argument is of type 'struct gzFile_s **'
gznbd.c:118:9: warning: passing argument 1 of 'gzerror' from incompatible pointer type [enabled by default]

This is because the zlib API uses just gzFile everywhere, not a pointer
to a gzFile.
