Check for error might have been needed

[irwir]

Comparing two code blocks, starting here

zlib/contrib/minizip/zip.c

Line 1414 in b8a8373

if (zi->ci.stream.avail_out == 0)

and here

zlib/contrib/minizip/zip.c

Line 1484 in b8a8373

if (zi->ci.stream.avail_out == 0)

In the first case err was assigned and checked after the conditional statement.
In the second case it was ignored and overwritten (as pointed out by cppcheck).
Either the assignment to err is unnecessary, or error condition should be checked.

@gvollant, could you please help with this issue?
