x86/mce/inject: Only write MCA_MISC when a value has been supplied
The MCA_MISC register is used to control the MCA thresholding feature on
AMD systems. Therefore, it is not generally part of the error state that
a user would adjust when testing non-thresholding cases.
However, MCA_MISC is unconditionally written even if a user does not
supply a value. The default value of '0' will be used and clobber the
register.
Write the MCA_MISC register only if the user has given a value for it.
