Subject: [PATCH] ALSA: oss: Remove redundant assignment to src_access

Variable src_access is set to 'dst_access', but this value is never read
as it is not used later on, hence it is a redundant assignment and can
be removed.

Clean up the following clang-analyzer warning:

sound/core/oss/pcm_plugin.c:472:4: warning: Value stored to 'src_access'
is never read [clang-analyzer-deadcode.DeadStores].
