ARM: net: bpf: improve 64-bit store implementation
Improve the 64-bit store implementation from:
ldr r6, [fp, #-8]
str r8, [r6]
ldr r6, [fp, #-8]
mov r7, #4
add r7, r6, r7
str r9, [r7]
to:
ldr r6, [fp, #-8]
str r8, [r6]
str r9, [r6, #4]
We leave the store as two separate STR instructions rather than using
STRD as the store may not be aligned, and STR can handle misalignment.
