crypto: x86/sm[34]: Remove redundant alignments

SYM_FUNC_START*() and friends already imply alignment, remove custom
alignment hacks to make code consistent. This prepares for future
function call ABI changes.

Also, with having pushed the function alignment to 16 bytes, this
custom alignment is completely superfluous.

( this code couldn't seem to make up it's mind about what alignment it
  actually wanted, randomly mixing 8 and 16 bytes )
