[Spice-devel] [PATCH v2 2/2] Fix set but not used variable warning

[Eduardo Lima (Etrunko)]

Introduced by commit 903c91cd3013c763abd3f2292f8fbd911a0c83f0, this
variable is used only for LZ4 code. Move the declaration to the proper
block of code.

Build log:

spicevmc.c: In function 'handle_compressed_msg':
spicevmc.c:346:14: error: variable 'decompressed' set but not used [-Werror=unused-but-set-variable]
     uint8_t *decompressed;
                   ^
