msm: ecm_ipa: remove IPA BAM dump logic for timeout detection

This commit remove the BAM dump in case of Tx timeout detection.
The reason for removing the BAM dump is that new locking logic
inside IPA driver does not allow being called in case a spinlock
is held.
Network drivers API are always being called with spinlock held,
thus, ipa_bam_reg_dump() can't be used.
