regmap: maple: free entry on mas_store_gfp() failure

Browse source

[ Upstream commit f3f380ce6b ]

regcache_maple_write() allocates a new block ('entry') to merge
adjacent ranges and then stores it with mas_store_gfp().
When mas_store_gfp() fails, the new 'entry' remains allocated and
is never freed, leaking memory.

Free 'entry' on the failure path; on success continue freeing the
replaced neighbor blocks ('lower', 'upper').
