crypto: sha1-mb - make sha1_x8_avx2() conform to C function ABI
Megha Dey reported a kernel panic in crypto code. The problem is that sha1_x8_avx2() clobbers registers r12-r15 without saving and restoring them. Before commit aec4d0e301f1 ("x86/asm/crypto: Simplify stack usage in sha-mb functions"), those registers were saved and restored by the callers of the function. I removed them with that commit because I didn't realize sha1_x8_avx2() clobbered them. Fix the potential undefined behavior associated with clobbering the registers and make the behavior less surprising by changing the registers to be callee saved/restored to conform with the C function call ABI. Also, rdx (aka RSP_SAVE) doesn't need to be saved: I verified that none of the callers rely on it being saved, and it's not a callee-saved register in the C ABI.
