KVM: arm64: Mark set_sysreg_masks() as inline to avoid build failure
When compiling with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, set_sysreg_masks()
fails to compile thanks to:
BUILD_BUG_ON(!__builtin_constant_p(sr));
as the compiler doesn't identify sr as a constant, despite all the
callers passing constants.
Fix the issue by always inlining this function, which allows GCC to
do the right thing.
