[PATCH] lib/zlib: remove redundation assignement of avail_in dfltcc_gdht()

[Tom Rix]

cppcheck reports
lib/zlib_dfltcc/dfltcc_deflate.c:65:21: warning: Redundant assignment of 'avail_in' to itself. [selfAssignment]
    size_t avail_in = avail_in = strm->avail_in;

Only setting avail_in once is needed.

Fixes: aa5b395b69b6 ("lib/zlib: add s390 hardware support for kernel zlib_deflate")
