alpha: fix the BUG() macro
The commit "alpha: teach the compiler that BUG doesn't return" (ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline function which takes __FILE__ and __LINE__ as arguments. This violates asm constrains there ("i" - an immediate operand with constant value), so that compile may result in warning or error, depending on compiler version. Just adding an infinite loop to the BUG() is sufficient.
