load_linux: return a non-void value to fix compiler warning

->boot_linux() actually returns an error value, so return it to the
caller of syslinux_boot_linux() and fix the following compiler warning,

com32/lib/syslinux/load_linux.c: In function ‘syslinux_boot_linux’:
com32/lib/syslinux/load_linux.c:527:1: warning: control reaches end of non-void function [-Wreturn-type]
