Takashi Iwai 333830aa14 gpio: exar: Fix bad handling for ida_simple_get error path 
The commit 7ecced0934e5 ("gpio: exar: add a check for the return value
of ida_simple_get fails") added a goto jump to the common error
handler for ida_simple_get() error, but this is wrong in two ways:
it doesn't set the proper return code and, more badly, it invokes
ida_simple_remove() with a negative index that shall lead to a kernel
panic via BUG_ON().

This patch addresses those two issues.

Fixes: 7ecced0934e5 ("gpio: exar: add a check for the return value of ida_simple_get fails")
