x86/paravirt: Fix build due to __text_gen_insn() backport
The Link tag has all the details but basically due to missing upstream
commits, the header which contains __text_gen_insn() is not in the
includes in paravirt.c, leading to:
arch/x86/kernel/paravirt.c: In function 'paravirt_patch_call':
arch/x86/kernel/paravirt.c:65:9: error: implicit declaration of function '__text_gen_insn' \
[-Werror=implicit-function-declaration]
65 | __text_gen_insn(insn_buff, CALL_INSN_OPCODE,
| ^~~~~~~~~~~~~~~
Add the missing include.
