arm64: kprobes: Fix Uexpected kernel BRK exception at EL1 (2021-01-22 16:05:29 +0000)

arm64 fixes:

- Correctly mask out bits 63:60 in a kernel tag check fault address
(specified as unknown by the architecture). Previously they were just
zeroed but for kernel pointers they need to be all ones.

- Fix a panic (unexpected kernel BRK exception) caused by kprobes being
reentered due to an interrupt.
