net: ipa: use a bitmap for available endpoints
Similar to the previous patch, replace the 32-bit unsigned used to
track endpoints supported by hardware with a Linux bitmap, to allow
an arbitrary number of endpoints to be represented.
Move ipa_endpoint_deconfig() above ipa_endpoint_config() and use
it in the error path of the latter function.
