zlib/gunzip: Use WATCHDOG_RESET macro
As usually done in U-Boot, the watchdog_reset code is called via a macro (WATCHDOG_RESET). In zlib.c this was done differently, by using a function pointer which is initialized with WATCHDOG_RESET upon watchdog usage or with NULL otherwise. This patch now uses the plain WATCHDOG_RESET macros to call the function resulting in slightly smaller U-Boot images and simpler code. U-Boot code size reduction: PowerPC board with watchdog support (lwmon5): -> 80 bytes smaller image size PowerPC board without watchdog support (sequoia): -> 112 bytes smaller image size Signed-off-by: Stefan Roese <sr@denx.de> Cc: Detlev Zundel <dzu@denx.de> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
