coredump: fix core_pattern input validation

Browse source

[ Upstream commit a779e27f24 ]

In be1e028302 ("coredump: don't pointlessly check and spew warnings")
we tried to fix input validation so it only happens during a write to
core_pattern. This would avoid needlessly logging a lot of warnings
during a read operation. However the logic accidently got inverted in
this commit. Fix it so the input validation only happens on write and is
skipped on read.

Fixes: 16195d2c7d ("coredump: validate socket name as it is written")
