tprintf: Fix compiler warnings
Fix the following warning when compiling with -W/-Wsign-compare/-Wunused-parameter: tprintf.c: In function ‘__tprintf_flush_skip’: tprintf.c:54:65: warning: unused parameter ‘max’ [-Wunused-parameter] tprintf.c: In function ‘__tprintf_flush’: tprintf.c:70:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] tprintf.c:76:18: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] tprintf.c:80:13: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] tprintf.c: In function ‘tprintf’: tprintf.c:131:10: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
