x86/microcode/intel: Improve microcode patches saving flow
Avoid potentially dereferencing a NULL pointer when saving a microcode
patch for early loading on the application processors.
While at it, drop the IS_ERR() checking in favor of simpler, NULL-ptr
checks which are sufficient and rename __alloc_microcode_buf() to
memdup_patch() to more precisely denote what it does.
No functionality change.
