msm: ipa: improve SUSPEND interrupt handling

When a packet arrives to a suspended endpoint in IPA,
IPA generates a SUSPEND interrupt. IPA driver handles it by
requesting the corresponding CONSUMER resource from IPA RM for
1 second and then releases it. In case this resource is requested
by another resource in IPA RM and released, the resource will be
released only after the 1 second timeout expires.
This change improves this by releasing the resource immediately
without the need to wait for 1 second timeout.
