Fix sparse warnings in init_boot_tracebuf()

core/trace.c:43:42: warning: incorrect type in assignment (different base types)
core/trace.c:43:42:    expected restricted beint64_t static [toplevel] [usertype] mask
core/trace.c:43:42:    got int
core/trace.c:44:46: warning: incorrect type in assignment (different base types)
core/trace.c:44:46:    expected restricted beint32_t static [toplevel] [usertype] max_size
core/trace.c:44:46:    got unsigned long
